MTD for TAS books gives VAT periods 1998 only

We use TAS books and have subscribed to the MTD VAT bolt-on for £25 per month (!). I can't do anything with it at the moment (!), because for the company whose VAT return is next due, I am only offered two VAT periods, both in 1998 (!). How do I find the current VAT quarter? Thanks for assistance, EL
