Lua error in Appearances tab

Found a weird error in the Appearances tab.

When right clicking on some transmog sets (like for example the Plunderlord’s Finery) a Lua Error window appears with the following:

I disabled ALL addons to make sure it’s not caused by a 3rd party one and… nope, the affected addon is “Blizzard_Collections”

I have the same issue too, it appears that it is being caused by the original Plunerlord’s Finery set from Plunderstorm not having a sub tag like the yellow set.

I have the same issue
