Inconsistency in Community UI can't tell if I'm subscribed or not

If the video doesn’t load try this link

On some comms the heart button (for subscribe) shows subscribe but if i open the comm and the “list” it doesn’t show subscribed on that UI.

Wait I realise I posted this from my non piefed alt, sorry if thats confusing but the issue is with my piefed alt.

Also if I click the subscribe button a UI pop up says “subscribed!” but the heart remains unchecked.

And FWIW this behaviour is happening but its showing up in my feed so I am subscribed in the backend.
