Created relation won't display as a source option

My app’s URL:

I have created several relations to link an inline list to a choice component. However, when I go to select the relation, it does not appear. What am I missing?

So do you want to have a relation’s values populating the choice component? Or do I miss something here with “inline lists”?

I created the relation, but it does not show up as a source to choose in either the inline list or choice component.

Did you check the “match multiple” box?
