FWIW, tried updating QB 2016 Pro several times, including several reboots of the program and the computer. Seems that the updates weren't happening. Finally boned up and bought the 2018 version, since they put it on sale (and I usually update every two years). Installed, updated, and now I get the "Capital One - Credit Cards" entry like yours - and it seems to work.
It oddly marks the "last updated" at various days prior to today, but it works. We'll see how it pans out.
Disappointed that my solution was to upgrade the product (at $180), but I guess that's how software companies stay viable.
