Font selector changes depending on font

This font:

Doesn't work. And more so, does this to the font selector UI.

When it is removed again, the font selector has columns again.

The font name has an apostrophe and an exclamation mark but renaming the file does nothing.
It is understandable that a poorly constructed font doesn't load, but that it changes the UI is a shame, especially since the same font works in other apps (tried Xara and Affinity apps). Just a niggle.
