Dreaded Grey Bubble from LookUp

I created a joined list of row-ids (JL-ROWS) in table1 from a Query.

In table 2 I did a lookup from table 1 (found via a relation) for JL-ROWS. It returned as an array instead of a JL (text separated by commas).

Thoughts on why this happened and how to fix? Thanks

Ugghh…just looked at the relation and saw that it was set to “Match multiple”

Nevermind!
