Is there an unreported bug with CS not updating Vars, and UE4.27?? (Ive found many threads reporting this issue.)

In the older version, someone could even set a Var in CS without setting it to Instance Editable.

Yet in UE4.27, I cannot set a MAP or Array var in CS, when both are set to Instance Editable (which I believe they changed - that it is now required to be on. But still CS wont update my Map or Array vars???)
