Early Adopter Group Issue boards not scope filtering correctly

Summary

Currently we are on the Early adopters plan and have just been given access to the issue boards for our group. I've noticed however, that the issue boards scope filtering isnt populating the list of milestones correctly, only having 'Started', 'Upcoming', 'Any Milestone' and 'No Milestone'. Is this the desired functionality?

What is the current bug behavior?

What is the expected correct behavior?

Filtering based on milestones should function like project issue boards.
