Commenting in sticky note and highlight

I am using Adobe Reader Continuous Release, Version 2023.008.20458, 64-bit.

I'll try to explain the problems in more detail.

I use commenting within highlight and sticky note frequently. It's in the last few days that it's stopped working properly.

In Preferences>Commenting, I have the font set at Arial, 12 point.

When I highlight text and add a comment, the text size of the comment is as expected, until I press the space bar, then the text reverts to a smaller size, and any formatting (bold, italic, underline, superscript, subscript) is lost.

A similar problem occurs when editing an existing comment attached to highlighted text.

If I add a sticky note and add a comment attached to it, then when closing the text box, the sticky note (and comment) disappears.

Also, throughout a document that has highlighted text and sticky notes, the positions of the highlighting and sticky note icons have changed slightly, and the sticky note icons have changed their size.

These are the problems I have noticed. There may be more, but presently I'm withholding from using the feature .

I would like to add that writing comments via highlight and sticky note has always had the problem that "remove all formatting" causes the text to become large, which can not be reversed, also if a special character is pasted in (e.g greek character from a symbol font) this will similarly cause subsequent text to become large.  

Thanks, I hope this helps.
