Copy and paste issue in custom exercises name and template name field

My trainer uses fitpros.io so I have to manually copy the workout templates into Bevel. I do this by having fitpros.io open on my Mac and copying and pasting the exercise name into Bevel, because they can get quite long. Often when creating custom exercises, when I paste the name it closes out of the custom exercise creation screen and sends me back to the list of exercises.

I would say this happens > 50% of the time and is extremely frustrating. Sometimes it works on the 2nd or 3rd try. Same happens when I try to paste a new template name and it kicks me back to the fitness tab.
