Hello, No, it is not a bug.
Depending on settings AB may not be able to open position of requested size. For example if you have turned off "Allow Position Size Shrinking" it may not be able to open position with desired round lot and min. shares not exceeding available equity. So it is recommended to turn ON (it is tuned on by default) "Allow Position Size Shrinking" or adjust position size or other settings (round lot size, min shares, etc) to allow position to be opened.
