HACS Error Notification Help

I installed HACS on my HA OS instance running on Pi4 without any problem. I did notice these two notifications when I open HACS and i was wondering if anyone could tell me what they mean? And also if you guys now how to fixed them if they are any kind of problem.

Had it shortly after I installed 2022.4 but went away over time, did not investigate a lot as all was working fine

The first one is only a warning that HACS is busy in the background. It does this from time to time to keep the repositories up to date. You can ignore this.

The second one means you are missing information for one of your installed Frontend cards. Go to the Fronted tab of HACS and see which one.
