Issue on Volume tool box set default 9999.00 value please help me to fix it ;)

 

Hi,

I have a issue since 06 May 2020 18h, my volume size in the order toolbox suddently changed, no reason why, as "9999.00" default value and I can't open a order at a other value. If I change it and enter 0.01 as usual, the Buy and sell button can't be select, it is gray. So I can't trade anyway. Tryied all things to set it up, close reopen, restart, webtrading, no way ! My account seams to be concerned.

I can't understand what the hell is going on and it's very enraging. What happen if I open a position with 9999.00 volume ??? The 9999.01/.02/.03/.04 Don't give possibility to open too, as 1/0.1/0.01 

Thanks to help me guys if you ever heard about this and if you know a way to fix it.
