The same situation happened for two consecutive days, 0.5 lots were entered, and suddenly it changed to 5.4 lots or 5 lots, which was basically the number of lots I could buy in full position. After that, I was not allowed to close the position. The first time I was fortunate to set a stop loss, but the second time, I was not allowed to set any stop loss and close the position at all, and forced me to liquidate my position. I made two transactions with the mobile mt5 and the computer version of the mt5, and it felt like I was hacked. Completely inoperable for the user. So do not use this broker, there is no way to quit.
