Hey @coatezy thanks for the contribution! I noticed that some tests are failing. Could you please share the tags field code from your resource and more details about how to reproduce the issue?

Hey, @Paul-Bob! Not problem. I'd be happy to try and understand why these are failing. The tags field is configured in the following way on the resource.

    field :tags, as: :tags, acts_as_taggable_on: :tags

I was able to reproduce the issue, I guess the tests are failing because tags cover several use cases and this change fixes this particular use case but maybe is breaking another use case, I'll also have a look
