Conflict using multiple taxonomy advanced fields in same block

I am running into in issue with having two taxonomy advanced fields that populate using WordPress categories for a featured content section I am building.

On the very first save, everything is fine. I select my category in one select field and another category in the other. However, when I go back to edit the block, they both somehow get set to the same category. I am able to then re-select and save and it works again until I go back to edit the page.

It appears there is an issue with using multiple taxonomy select boxes that pull from wordpress categories. Somehow on page load they are setting to the same values and I have to re-choose them again and hit save.

Just to clarify the two fields I am referencing are "fallback_category" and "autopopulated_single_category"
