Cant buy Darktide after playing the Beta

[DickMuncher]

Whenever I try to buy darktide, I get this message: You cannot complete your transaction because you are attempting to purchase an item that is already included in another packaged item in your cart. Please check your cart to verify that you are not purchasing an item multiple times. The most common cause would be purchasing DLC along with a deluxe version of a product that already includes the same DLC.

Ive had the beta completely deleted from my steam and my computer, so how do I get rid of this? I just want to buy the game...

if it was the pre order beta, the beta is the game you launch it normally as if ou were still playing that, if it was the invite only beta i have no clue.
