Cable card stopped working

Yesterday, I went to a Xfinity store to get on another promotion (my account has 4 cable cards).  When I got home, I noticed that one of the devices was no longer having any signal coming from it, so I tried the following

1. Went to the self service cable card activation site (thank you for bringing that back) to re-pair to the device and while it said it was successful, I was still not getting any signal
2. Tried pairing the same card to another device, but got an error saying it wasn't successful
3. Tried pairing another card to the same device (from step 1) and it was successful and I did get a signal.

When I look at my account and the devices, I'm now only showing 3 devices, which makes me wonder if the card that I'm having issues with (all of a sudden) was removed/"returned" from my account. 

Can someone look at my account and confirm if I still have 4 cards or if one was removed?
