Hello,
You need to click upload to ankiweb.
Please see this: Should I click upload to ankiweb or download from ankiweb?
First, restore all your notes by doing this:
Please try resetting your local changes. To do this:
Go to browse in your Anki → at the top click on ankihub addon tab → press reset all local changes
This will restore everything to what AnkiHub has unless you have specifically protected those fields
Then click sync → upload to ankiweb
