Sell Return Issue With Cash Register Details

[magedfathi]

1- when make a sale with 20 QR then make void sale >> still the sales amount in cash register and dashboard the same not reduced 20
Also when make sale return and select deduct from cash register, the cash register and sale amount keep the same and not deducting. also return order amount in cash register always zero

2- why i can report bug for MOS, i am getting error that i already bloced earlier from reporting a bug ??
