Protected field "Extra" cards are missing in Errata v12

Hi! I recently upgraded from ANKing Overhaul v11 to ANKing Overhaul v12. I protected my “Extra” field and then imported $Errata v12 cards to my Anki, which were updated.
I found that not all cards with their “Extra” field modified are in the $Errata v12.
Is there any way to get to know all the cards with the modified “Extra” field or both “Text” and “Extra” fields?

Hello

I am not 100% sure what you mean but $errata v12 is in AnkiHub and therefore you will not need to import your own errata v12

Also, thousands of cards were deleted from V11 to V12 since they were either duplicates or extremely low yield. That might explain why some are not there

Let me know if I am understanding your question correctly though!

If there is any change to the “Text” or “Extra” fields, those cards are included in the $Errata, is that correct?
I followed the AnKing video: https://www.youtube.com/watch?v=TTHpODHBk3U (13:20) where he showed what to do if one is protecting “Text” or “Extra” fields.
So I exported the $Errata v12 cards and then imported them back.
