I'm having a GREP issue in InDesign CC2017.1, I tried saving three different GREP queries but it saved the first one three times. I tried about three times to go back and correct the other two, but it would just remain the first GREP query. It seemed to only affect the Find field, what I saved in the Change field seemed to be fine. The only way I could get them all to save correctly was to physically go into the GREP XML files and enter my GREP query and save. I'm using OSX 10.10.5
