The use of diactrical marks changes font of forms and disturbs appearance of text fields
I am using the Polish version of Adobe Acrobat Pro DC on macOS Big Sur. I have been having trouble filling out forms for some time. When I enter any Polish diacritical marks in a form field, the program automatically changes the font, and in addition, the letters stagger or overlap, which makes the filled out fields completely unreadable.
Please find below an example of filling two fields with the same text - without Polish diactrical marks and after using them.

I've tried in the "Edit Content" panel under Preferences to set the replacement fonts to standard system fonts (like Arial, Times New Roman, etc.), as well as changing the font for comments in the "Commenting" panel. Unfortunately, this didn't do anything.
Of course, I have the application language set to coincide with the system language. Please help me in solving the problem.
