What? This shouldn't be happening.
You mean you don't see them in the slavers guild? Something might be wrong with your outside.gd. What you can do is turn off arcis, turn it on again (which should re-start a clean arcis mod without my modifications) and apply the outside.gd changes manually to the file (as written in the .txt file). In other words, don't overwrite outside.gd, replace the two changed lists (shops and treasure) in a text editor.
