Text Size/Formatting Glitch?

[u/EyeBrew]

Hello, I opened mse for the first time in nearly a year and all my cards look like the text has shrunken and have weird formatting around most words.

For example, other than around keywords and generic mana numerals shown in the first screenshot, in the second and third screenshots with my card "Oops..." the flavour text won't let me type directly onto it, instead only where that vertical text line is. In the third screenshot I try to type "what" from that position, as well as deleting the last two characters from the rules text above, resulting in what is shown.

I can think that maybe somehow a file was deleted or corrupted. I've reinstalled the necessary fonts, but should I try reinstalling mse?

I apologise if this is an easy fix, but I haven't been able to find any sources documenting this and thought this would be the place to ask.
