We made some changes to the AnkiHub add-on to make it update AnKing note types to their newest versions. This is why your customizations got removed, and we are sorry for that.
To solve this issue, you can use the AnKing Note Types add-on:

It has an UI for customizing AnKing note types. It also updates note types to their newest version while preserving customizations.
The AnkiHub add-on won’t update the note types when you have the AnKing note types add-on installed, in order to not remove your customizations.
