pre order showing alpha game time played?

pre ordered the game,one thing i did notice after we played and tested the alpha,even after the keys were revoked for the alpha like before it shows on my pre order sandstorm in the steam games list ive played it for 12 hours?

its highly unlikely i will want to refund this BUT if i did doesnt steam hold true on anything after the 2 hour play period
is a no joy on refund.
might be just a bug but interesting non the less

Just explain it how it is when you refund.

Valve shouldn't restrict you from refunding since it isn't the final product and you paid for the final product, so once you get it...only then should the hours really start to matter. However, just explain the situation and they should understand you.
