Custom fonts not working properly after the theme update


I just updated the theme and now I have a problem with my custom fonts. The fonts are too small and not all of them are showing at all. Also the image capture texts are not working properly. When trying to edit the text sometimes the editing bar don´t show and when trying to change the colour in some cases it changes the font size.

How could I fix this? I granted access to you already.

Thank you for your help!
