When you get too many behaviour bundles, you can’t see some of them. Also, deleting behaviours would be nice.
I had the same problem actually, I tried to make a new bundle a few days ago but it there was no space left for it because of all the other bundles I’ve made.

Hold down on the behavior you want to delete for like 5 seconds and a wheel will pop up.
Click delete to remove the bundle from your bundle list.
