Laying NBA Betbuilders, smarkets still on "ASK"

How does everyone lay nba betbuilders? I got the betfair offer but on smarkets it wont let me lay for example moneyline + over 234.5 doing the switch to sell method.

On the "winner and over 234.5 market" it just says "ASK", even though the event is in like 4 hours :/
