TrueNAS incorrectly considers OpenZFS 2 datasets as locked

I have a pool which is encrypted using OpenZFS 2 native encryption. However, recently when rebooting, it will not mount SMB shares because 

SMB share "{name}" is unavailable because it uses a locked dataset.

Similarily, if I try to change the home directory of a user, it errors with 

Path component for "Home Directory" is currently encrypted and locked

The pool automacitally unlocks upon boot.

Please let me know what I can do to help debug - I have no experience debugging FreeNAS/TrueNAS, but am happy to learn. I suspect the issue lies with pool.dataset.path_in_locked_datasets, or one of the related calls.
