Not Able to Bulk Edit Multi-Select Option Set Fields?

We recently updated to Dynamics 365 Online 9.0 and want to utilize the new multi-select option set fields. I've created a new multi-select field and am looking to add data to several records at once using bulk edit. When I select multiple records and get to the bulk edit form, that multi-select field doesn't show up to update.

Is this expected behavior? Are we unable to use bulk edit to update multi-select fields? I haven't found anyone else talking about this online so I'm skeptical.

I've check form order and don't believe that's the issue. The multi-select field shows on the regular form fine, just not when I go to bulk edit.

Any help is appreciated.
