Servant not Placing matched SP bets

[Blackpowder64]

Hi I am using a servant to place SP bets some times it places the bet other times it does not..
I just placed a £100 SP bet via servant and it did not place the bet? It does place the bet but did not match ? Very annoying How can i see whats going wrong?.The servant goes ding! then indicates amber then goes red?
This has happened several times
Whilst i write this just placed another SP bet it worked but did not indicate red dot next to the bet? the only way i could see if it was matched is by looking on betfairs webpage matched bets?
Thanks

Most likely is that on your parameters page you have something other than "No minimum price"
