getting INVALID_ODDS for lower price using "fill or kill" feature

[betfairuser]

Hi,

I'm trying to place bet with lower price than available, but I'm getting invalid odds result, the "Best Price Execution" feature is enabled.
The price I'm using is not in the available prices list, but otherwise it is valid prices for the selection.
As it used to work, it may be related to the "kill or fill" feature I've started to use.
