This group trade thing is all fucked up.. cost me a lot of money

i set all 8 of my 300k accounts up in the group at the same time 6 got blown, yet 2 have open positions and in profit , making no sense



have the group set up for 8 300k accounts with a quantity of 4
when i place trade under the group i need to buy 32 contracts 8x4
yet when i try to sell my remain 4 contract in 2 account i cant manage them individually b/c when i try to switch the quantity to 4 it tells me it needs to be 32 … this needs to be simplified

making absolute zero sense
