Hi @sgallese, I think that is correct and it’s a result of some changes between older versions of retool and not wanting to break any existing apps by modifying/removing the property. We are working on a feature now that may change the property to reflect the visible and calculated columns with their mappers, but we need to be sure it won’t cause issues for existing setups. I’ll add in this post as a note on that project and update here as we work on it.
