Product Variants/Options dont "lock in"

I am Building a Shop for Fishing baits so i have 3-8 Colors per bait. With the fist 6 Products everything went normal but now i cant “lock in” the Variant names. Normally i type the name and press enter and it gets blue, but now after 3-4 variants presssing the enter button after the word makes a paragraph just like in the screenshot.

Does enybody know what i can do about ist or if there is a way to work around that?
