Replacing those 63 instances of 'pos1' with 'slave' fixed it, though I did have to deactivate and reactivate the mod, then create a new save and load it before it worked. Thanks ankmairdor!
I'm running into a problem with body images where they double up in the talk menu, with a slightly larger one appearing behind the default regular sized one after selecting "Let's stop and talk". How do I fix this?
