Basically, “everything”.
Most importantly, the Form panel needs property shapes to display property
values.

Okay. We test this feature with various examples and I have not seen this
happen. Ontologies being what they are, our tests can cover only a selection of
the possible cases. So sometimes there are bugs.
Can you share your ontology, or better yet, reduce it to a minimal example that
triggers the problem, so that we can investigate, fix any bugs for the next
release, and perhaps advice on what specifically triggers the bug in the
current release?

Which version of EDG is this? In 6.3.2, “Convert OWL Axioms to SHACL
Constraints” creates URIs for property shapes and not blank nodes as shown in
your snippet, so I'm confused as to what steps exactly you took.
