Error when selling in Auction House

Heya ..

im selling my trash item to Auction House , im believe my price is lowest in Auction House .
but in first and second page i cant see my item ..

example :

me : sell silk cloth for 10 gold --> lowest price
somebody : sell silk colth for 12 gold --> higher from me

but in first and second page its full for silk colth for 12 gold and my item at third page :3

its normal or not ??
or im dont understand with Auction House system ??

Thankies

*my duration in AH same like person who selling for 12 gold
