EE Keeper and multiclass kits.

I am sure this has been asked many times but trying to make a cleric/swashbuckler with EEKeeper. When I switch it around, restart at level 0, I get the swashbucjler AC bonus and all is good with that but I also keep the backstab multiplier. Is there a way to turn that off? Will I get the HLA for Swashbuckler at high levels or will that need to be manually adjusted like the weapon skills?
