Is there a way to reset a kit max? Without having to redo the whole kit?

Ex) A kit is currently set at 1. I want to remove the max limit all together and just have a cooldown. Which I already set the cooldown. 

Editing the kit and trying to just write max with nothing after it, doesn't seem to do anything.

Update: I ended up going into the data file and changing max: 0 since i kept getting an error trying the command :)
