Not letting me book practical test for car category even though I have passed theory

I am having a bit of bad luck I think, I passed the theory test Friday there and tried booking the practical on Saturday (let them register the pass on my licence) but I cannot book it at all as it tells me I can't choose the car cat , but choose the bike unrestricted mod 1 test and it was letting me put my pass certificate number in I think it's maybe an error on dvsa maybe ? Can anyone reassure me or should I call dvsa and find out ?

Thanks for the reply I was optimistic about this site for answers but that sounds reasonable to be fair thanks I will call them tomorrow just to confirm this anyway.

This site has @IWMTom on it, of course you're gonna get good answers .
