Something is intermittent here
First the import using add-ons works
I was adding the add-on list one by one. Initially the Item I was adding was not disappearing from the add-on list, despite a message that said the add was successful.
Then it started acting "Normally", with the addition "deleting" from the list as expected.
After I had added several (most) successfully, the entire list reappeared, including all those that I had added.
