Adding new PMF model to Field breaks "Show Model Structure"?

[LenLon]

What happened?

Hello, minor bug:

Whenever I add a PMF model to a Field where there is already a PMF model present, clicking "Show Model Structure" expands the tree, but none of the items are themselves expandable:

Barley (from Barely example sim) looks fine:

Adding maize, then expanding model structure:

As you can see, none of the items are clickable. So I can NOT look at cultivar parameters, for example.
Is this intended?

When I delete barley, it still does not work. When I delete all crops and readd one, it STILL does not work. 😓
