Unable to Deleted Tag Folders In Version 7.6

Hi Team,

I was facing issue on Deleting the Tags in Ignition Version 7.6.
Though the actual tags were Deleted but Folders structure was unable to be deleted.
(Ex: if you have a Client tag inside the folder Area1->Room1->Temperature, Here Client tag Temperature is getting Deleted but Area1 and Room1 Remains undeleted though i tried Deleting the Entire Area1 Folder.

Please suggest me what has to be done in this case.
