Subdecks not showing up

Hey guys, so after the new Ankidroid update I was unable to open up and view my sub decks of one of my heading decks…Surprisingly the problem occurs in only ankidroid and not the PC version of Anki…Also the problem is only with one deck, the rest of them open up normally to display all the subdecks…However, I am sure that I have not deleted those cards because they do show up on the card browser in properly arranged sub decks…Anyone else had this problem…any fixes you guys can offer…pls help.
