Bugs or Unexpected Behavior

Describe the bug
I'm trying to add a 'Run Real JavasScript' action within the Stream Deck section. For the Source Type, I choose "Source Type: Real JavaScript" and type valid JS (confirmed as I use the same script in a menubar item action). When clicking away/saving, the Source type changes to 'Apple Script from SCPT File' and thus the action does not behave as expected.

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):
Stream Deck (Beta)
