Confusion on football pre match ladder

[pennybridge]

Having logged in practice mode. The racing market seems accurately to follow what is actually happening but on the football market the total on the match is £740 but actually on betfair it is over a million. Finding it hard to practice when it is not reflecting what is happening. I also logged in not in practice mode (very carefully) and again it only showed £740. Have I pressed or set something wrong. It works on horse racing. Help would be gratefully received
