Unknown column 'su.status' in 'where clause'

I have noticed other issues with unknown column 's.status', but none for this specific issue. I checked status reports, and there are no database updates pending (and I updated the DB anyway, to see if that fixed the issue).

I migrated from a D6 site to D7, on the D7 site I get this error whenever I try to view subscribers.

Thanks.
