Heya ! That was a tiny bug I fixed few weeks ago, just by updating current 1.2.2, so even if you have 1.2.2, it may still contains the bug if you haven't redownloaded the mod recently. When did you installed the mod ?
If you don't want to make a whole new install, you can just download 1.2.2 again, and replace the www/js/plugins/Yuti_Private_Cell_Interrogation.js file (where you installed the mod) by the new one.
