Shapeshifter tokens for sale in stores??!

I've encountered a weird bug whereby shapeshifter tokens and other strange things are for sale in stores when they're clearly not supposed to be:








I realise that this is something to do with mod compatibility, or some mod installation error, but I was wondering if anyone could give me any pointers as to where the problem might, before I go randomly uninstalling and reinstalling things.

My setup is BGEE 2.3.67.3 running on MacOS 10.12.6, bought directly from Beamdog.

I've installed the following mods, in the following order:

1. SCS Mandatory hotfix
   
2. BG1 NPC project
   
3. BG1 NPC music
   
4. BG1 unfinished business
   
5. BG1 NPC portraits
   
6. Scales of Balance
   
7. Stratagems of the Sword Coast
   
8. Tweaks Anthology
