4.2.7, can't select events in blueprints

Testing FMOD for an existing project in custom 4.2.7 build from VisualStudio

Playing from this works:

However i can’t select the event from a blueprint script, every time i click it, it just resets to blank.

It could be helpful to increase the logging level, both in FMOD (Logging Level to LEVEL LOG) and in the Integration (Additional Logging).
Hopefully this may be able to shed some light as to why this is occuring.
