Feeds added before upgrading to Premium Archive are all marked as read :(

I imported a bunch of feeds and then upgraded to Premium Archive, which I guess I did in the wrong order and now all of the archives are marked as read.

If I add a new feed now (after upgrading) then all the archive gets marked unread, is there some way to get this to apply to feeds I’ve already added? Deleting and readding them doesn’t seem to fix it.
