Spelling Problems after Update to 3.6.8

Hi, i am having Issues with the Notes in Mindmaps, when i excerpt text, it will be shown as interrogation marks. Then the excerpted text will be converted to lowercase and ignores the spelling of the original text (Capitalize).

This Problem is new since the update to 3.6.8.

Thank you for the Help.

Hello, this place is not a problem with version 3.6.8, because your pdf uses an OCR text layer that MarginNote3 cannot recognize, so the excerpt is in ???
What is displayed will automatically be corrected to more accurate text content when networked, but uppercase and lowercase have different effects for different PDFs and may not distinguish between uppercase and lowercase.
