more than one bet placed -dutchbets

[slochin]

Hello,
I would really appreciate some urgent assistance please.
I have a spreadsheet that places bets on my two selections for the race staking dutch bets.
Today for some reason it is placing the dutch bet on each selection then placing an extra bet on one of the horses.
It has worked properly before and I tried it again early to make sure it was right with some aus racing and it placed the bets correctly. I am at a loss as to why this is happening.
My formulas are in AA 1
=IF(AND(E2="Not In Play",F2<>"Suspended",OR(D2=TIMEVALUE("00:01:00"),ISTEXT(D2))),"Yes","No")

and in q5
=IF(AND(COUNT(T5:T60)=0,S5<>"",R5<500,$AA$1="Yes"),"BACK","")
the example of the first race

Now the bets placed at 23.57 are correct for my dutch bets of $20 but not the next one.I don't understand why it is placing that bet .
