What’s the default sort option on Lemmy’s Web UI? I don’t remember if it is synced correctly.

The default sort at least used to be Active. It might be Scaled now for newly registered users.

Regardless OP, it’s possible you have to change your default sort on user level in the Web UI. The setting there at least used to override Sync’s setting, that’s how you could use Scaled sort on Sync before it was officially implemented.

I’d start looking there.
