Sensor.hacs doesn't update

I have three Home Assistant installs running. On two (both HassOS, one in VM one on Raspberry Pi), the sensor.hacs never shows anything but 0. On my main (soon to be deprecated in favor of HassOS VM) Home Assistant (core in Docker), it seems to be the opposite, it shows three updates, but navigating to the HACS panel, I can see that there are no pending updates.

So I’m guessing the sensor just stopped updating at some point (for all three installs). Why would it do that?

While looking at the sensor displaying 0 updates (for the VM), I can navigate to the HACS panel and see 5 pending updates. I can also update them just fine, but without the sensor ever changing. A search on the HACS website yields not results. Any idea what’s going on?
