Sqltags browser corrupted

Ignition 7.5.6 (b1317) trial

Have a UDT “PAC3200” with folder structure and OPC tags to communicate with Siemens PAC3200 power monitor.

Created duplicate tagname in UDT, to that added manually in an instance of a PAC3200 UDT. This appears to have been cause of problem.

Image attached.

Windows using the PAC3200 instances remain running so it appears to be a browsing bug.

Have tried to remove the duplicate tag in UDT but problem persists.

Console shows

Really odd.

Restarted Gateway and the PAC3200 Instances replaced by folders in SQLTags Browser with the same name as PAC3200 instances.

Could not delete/rename folders.

Restarted Gateway again and these folders are now gone.

Recreated PAC3200 instances and everything working again.
