I’ve imported my collection from DVD Profiler and it went okay.
The biggest issue I have is that all my Blu-ray and 4K movies were tagged with BluRay and UltraHD tags in the "Edition”, “Format” field.
I was able to add the correct Blu-ray and 4K UHD tags but how do I remove the other tags in bulk?
The “Edit xxx movies” dialog shows a set of checkboxes for each of the "Format"s in my collection but none of them are checked so I have no way of unchecking a format.
I think both @twazerty and me read your first post wrong. It seems you are talking about the Format field. The same instructions apply, just use them for “Format” instead of the tags field
