Unlock progress not syncing between different PCs?

I’ve been playing the beta in WorldBox on two different PCs using the same Steam account, but I’ve noticed that my unlock progress isn’t the same between them. Things I’ve unlocked on one machine just don’t show up on the other.

I thought this might have been fixed already, so I’m not sure if this is still a known issue or if something’s just not working correctly for me. If anyone knows what might be going on or how I can fix this, I’d really appreciate the help!
