[ISS Support Case] Deleted MDAS tags still show up in HC Trend
Last updated: October 17th, 2025Description
Needed to delete several objects in IDE. History was enabled for these objects. Even after IDE deletion, these objects still showed in the Trend app; no new data, just the old history data that was collected. I deleted from the historian in the manual tags section, then deleted in the Trend app. I verified they were gone in all 3 places. However, when I deploy another object in the IDE, for some reason these objects show back up in the trend app - they do not reappear in the IDE or the Historian manual tags. Need to get this fixed and curious what other source the trend app might be pulling data from - or is there more than one location in the Historian that i need to delete objects from. Thank you,
