Paper.io recently got an update which includes having 5 different modes to play from instead of the one now "Classic" mode before. I'm trying to make subcategories for the runs on the leaderboard, but I'm not sure how to move runs over to those subcategories.

This is how it is before adding the subcategory: https://prnt.sc/kdpe2l.

This is how it is after adding the subcategory: https://prnt.sc/kdpdi0

Is there way a way to moving all the now "Classic" runs into the subcategory? I just want to make sure I don't accidentally delete any runs by mistake.
