I’m pretty sure I know the answer. It isn’t because you are a lumper, per se, although that sort of has something to do with it. When you export citations out of RM that are generated by templates, RM has to convert the citations to what I will call “GEDCOM standard” for lack of a better term. In doing so, all the Master Source variables are grouped together, and all the Source Details Variables are grouped together. And when I say RM “has to”, it really does have to. The receiving system may not understand RM’s source templates. The only thing available to the receiving system is going to be “source variables” as one item and “citation variables” as one item. These may or may not be be mangled as compared to the way they appeared in RM. It all depends on how the citation sentence is set up.
This is a well known problem, and there really isn’t much RM can do about it. Well, the source templates could have been designed so that all the “master source” variables were to the left of all the “source details” variables in the citation sentence. But then they probably wouldn’t have been compliant with Evidence Explained. The template you are using in your example is pretty egregious in not having “master source” variables to the left of all “source details” variables.
I’m an extreme source splitter and I use custom source templates of my own design. As a result, my citations are never mangled, no matter the system to which they are exported. And I’m sure that I am not 100% Evidence Explained compliant. Here are a couple of examples. All variables in the source (AKA master source).
U.S. Federal Census: 1940, Anderson County, Tennessee, Dist. 9, Enumeration District 1-14, page 243a, ancestry.com (1940 U.S. Census) viewed on 24 November 2014.
Notice that I don’t include family ID or dwelling ID or name of the person or anything like that. I cite to the census page. Period. There are nearly always multiple people per family and often multiple families on the same page that have the exact same citation. That’s what make sense to me. I don’t use repositories per se because there are usually so many places to find the same image. But I do make note of when and where I found the image. But the Web site is not entered as a repository.
Death Certificate: Peters, Alva Edward; Certificate 27359; Edgemoore, Civil District 9, Anderson County, Tennessee, 1942; ancestry.com (Tennessee, Death Records, 1908-1958); viewed 29 September 2015.
To me, the important thing is that this is the death certificate for Alva Edward Peters, so that’s what I put first in the sentence. The rest is fluff as to where to find it (well, where to find it actually is important, and is not just fluff). But a typical source template controlled citation is going to put the person’s name in the citation (AKA Source Details) rather than in the source (AKA Master Source). So my sentence which is logical to me only works for export if I’m an extreme source splitter. It wouldn’t work for export if the deceased person’s name was in the citation (AKA Source Details).
There is one more minor issue that is related. The sentence for a source template often has fixed text, not controlled by template variables. All such fixed text needs to be to the left of all citation variables (AKA Soure Details variables) to avoid the same kind of mangling.
My discussion is moot of you are exporting to RM or if you are exporting to software that does understand RM’s source templates.
