Removing suffix from batch generate preset crashes RF

[FosterType]

Hello!

First of all, thanks for making this script, I use it almost every day and love it. Just wanted to give a heads up if I you have a preset that has a suffix and then you want to remove that for some reason it breaks RF. It's not a big deal, right now I can work around it, just means being aware of the issue and removing the only preset and readding it.

Cheers, Dave
