Right…switching from multiple to single (or the other way round) results in loss of data columns. There was one time that they all came back, but often I’ve had to start from scratch with recreating lookups, and other columns/components based on those lookups.

I think Leaders need to look into it. It can’t be a bug then.

Will do, thanks, Mark! I actually did see a new warning the other day when attempting to switch from single to multiple.
