Question about add-on Rematch

I use Rematch for all my pet battles and before this latest patch I had it configured where I could switch to the pet I wanted to use next during a battle by using a hot-key. I downloaded the add-on again today, and for some reason I cannot figure out how to configure the hot-key. So, for example, the team has 3 pets and during battle I would press the F1 key to load the pet in position #1, F2 for pet in position #, etc… However, that’s not working now. Anyone know how I set the key for each pet position?

This is not the place for this. As it is related to an addon.

I entered this in the Battle Pet form, not bug reports. Wonder if someone moved it here?
