Q. How do I remove or delete multiple tags that are associated with the locations?

A.  With the Power add-on you will find additional Bulk Actions under the Locations/Manage panel.  There is a  drop down menu under the Bulk actions tab that can be utilized to remove many, some or all tags associated with the location data.  Check off which locations you want to remove the tags from, or you may check off all and select the filter to “Apply to all”

Bulk Action with Power allows you to remove tags
