DG 24x Variant Manager Warning

Hello!

I noticed that sometimes when working on Variants in the Variant Manager a warning logo will be displayed next to the Variant when some connection is unresolved. Sometimes it shows the following message:

I have no idea where should I go to check this "detailed view" and I didn't find any guidance in the documentation. Any idea on how I should proceed?

Also, I believe there's a bug in the VM where the warning sign won't go away even if you fix the issue.

Thanks

Jorge
