Hi @Joel_Walley, and welcome to the forum.
Condensing is not (jet) optimised for vocal+lyrics. But in homophonic passages can work.
With condensing issues especially, it is helpful if you could upload a cut-down version of your Dorico Project, to avoid the need of recreating your situation based solely on the screenshot.
(In your case probably would be enough to place a Condensing Change on the “and”, check-marking the singers in the dialogue, but difficult to say, without having the Dorico Project)
Please see this important thread, in particular Nr. 4.
