Technical problem with Covid pass expiry date

Has anyone else had trouble with the NHS Covid pass site?

DH and I both registered. We're both double jabbed, boosted and recovered from Covid in October.

My account shows all three of my vaccinations, and a pass expiring in 30 days, just as expected (though I wondered if the fact that we'd had Covid should have appeared there too?).

DH's, on the other hand, shows none of his vaccinations and the pass he's offered expires in 2 days time (I think that should be the case just for those who haven't had the jabs, but have reported a negative test, which he hasn't).

He's rung 119, as directed for any problems, and they claim they can see details of two of his jabs in his account, but not the booster. Their bright idea was to keep logging out and back in (we'd already tried this several times over a few days), and to try printing off the pass, because it might show a different expiry date when printed. Of course it doesn't!

I've seen that a few people have said on Twitter that they've had this issue, but none of them have reported it being resolved.

Has anyone had this problem, and if so, how have you sorted it out?
