This is a new version bug. When setting up a tab page, there is an additional tab at the top to fill in the storage field.
Hello,
Thanks for reaching out.
The tab field must be added first or moved to the top of a field group. Then you can add other custom fields below a tab to show them in that tab on the editing post page.
