small change to the order opening panel (important)

hi. i have noticed a bug (at least that's how i see it)
when i try to open an order, let's say i have put my stop loss at a solid bottom and i want to risk 1%. changing the StopLoss Risk percentage should change the Lot size not the price. because the trader want to risk some % of his account at this bottom.
in short, when i set my stop loss, let's say 70 pips. the platform automatically shows me the risk that im going to take. when i change the risk percentage, the panel changes the pips instead of decreasing/increasing the lot size.
please fix this.

thank you !
