Printing with out a raft and other questions

I just recently got a rep mini and I noticed on MB desktop/print that I can't disable having a raft in it. Is there any way that I can disable that. (I've made a custom profile in desktop and manually edited the JSON file.) but every time I try to print it doesn't extrude in desktop and then I can't select a print profile. It only has balanced as an option then if I try to print without a raft in print it gives me an error saying "ReferenceError: botTypeIsBirdwing is not defined" any ideas what's going on?
