Notes not saving

I am using a PC with Windows 11. Update version, the latest. Just discovered when in edit person screen and next to the person name I clicked on the Notes column. The Notes screen comes up on the right side. Entered notes and check the check mark to save. Clicked the < to go close the Edit Note screen. The note was not saved. It disappeared. Entered the note again and this time clicked on the Spouse or on a Fact and the Note was saved. I am sure I have lost several notes in the past if this has been happening. When entering notes must always check to make sure they have been saved. Have sent email to support about this today.
