Well, they both tested within one percent of 75, and or ambient RH is in the single digits, so I dunno...

I've never salt tested, normally I just use a 72% pack. I assume 75% is the target for that test?
If that's the case, I suppose I'd just say it's time to replace. Maybe they really do have a finite life to them.
Now another thought, pull them out for a few days and let them sit on the counter or even in some old boxes where they can give up some humidity. Possibly that could allow them to start taking up again.
OK, so I salt tested both. They were both within 1% of 75, so that seemed good and I calibrated them (they are adjustable). Then I stuck one in a zip lock for 12 hours with a 62% boveda and it reads 69%... FFS.
If you have any higher % boveda use those instead. And find an unused pack since your questioning the ones you're currently using.
I am going to try fresh batteries next and see if I can get a different result.
Old 65% bovedas in humidor - Read 68-69%
Salt test 24 hours - calibrated to 75% (was only off one or two %)
New 62% boveda in zip lock - 68%
I'm of the trust the boveda camp, but your readings are over threshold which would make me think your salt test would have been over as well, but it's not. I'm as stumped as you.
Do it for 36+ hours….maybe even 48.
After salt calibrating, both hygrometers read +/- 1% on my old 65% packs, as well as on a handful of the smaller 69% ones the shops send deliveries with. The brand new 62% packs are the only ones now reading 5+% higher than the printed value. Anyone ever get a bad batch of 62% Bovedas?
