Can't set original deck as home deck

I’ve deleted the Anking (ankihub) deck and tried to set my original Anking deck as my home deck, but it doesn’t show up as an option (even as a subscribed deck). When I go to ankihub and subscribe (again), it tells me that I don’t have the deck installed and I must install it.

I don’t love having two anking decks and I’m not sure how to fix this.

Just click install and it should populate to your old anking deck. If not you can manually move all the cards in the anking ankihub deck to your old deck
