paste text button/action not recognized

I mainly bought BTT so I could install special nordic characters/keyboard-buttons on the touchbar (via paste text action), instead of having to buy a new laptop as I am studying in Europe from the US with a US-keyboard.

First installation around mid-august was flawless. Every update since then has made the paste-action extremely buggy.

Everytime I press any of the touchbar buttons (whether Æ, Å, Ø, etc), BTT won't register the action. I often have to press the button 2-5 times before the character appears wherever I'm typing on - the search bar, a word document, or whatever.

Extremely annoying, especially when I have to do homework. I also have very important Uni-entrance exams coming up in November, so I'm nervous this will slow me down.

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):
Touch Bar
