Ok, so the thing here is that since you did not create a title for your images, X3 will create the title for you based on the filename. When X3 attempts to create a title from filenames, it will Capitalize, replace certain characters (_-) with empty space, and remove the extension. That way, a filename "neuer_weg-2.jpg"
will become "Neuer weg 2"
. So your option here is to actually use the FILENAME instead of TITLE, but first please update your X3 to latest X3.30.0 (Panel > Tools > Updates).
After updating, you can find options in Settings > Popup > Caption that allow you to specifically assign the filename (with or without extension). Likewise, you can find in the page settings > gallery > captions, options to assign "filename" and "filename_ext" instead of "title". This way, X3 will not attempt to make a title from your filenames, but will simply use the filename (with or without extension). That way, you will keep your filenames with lowercase.

Unless the questions are of a private nature, please post in public.

Simply wrap your text in a <p> paragraph:
