New Portal Designer (In Preview) Designer not Validating Connections Properly

P4 - Low (Cosmetic/minor inconvenience)

### Describe the Bug with repro steps

The new designer shows the old connection as an option and says it is invalid:

Connection choice still shows the option as upper camel case:

Is it cached?
