Cards that have blurred out "View on AnkiHub" button


A while back (~5 months ago) I upgraded from V11 to V12 infinity. I realized that there are some cards that have a blurred out “View on Ankihub” button in the bottom left corner. When I go to view them in browser, it says they have no Ankihub ID. What happened to these cards?

These were either duplicates or extremely low yield/unnecessasry and were removed.

You can find more info on the wiki and update log

Is there a way for me to know which cards are NOT synced to AnkiHub but in the Anking deck? I also see that many of the Lolnotacop cards are not synced to ankihub
