[4.5.0] MM does not work as setting

I imported a portfolio developed with SQX in QA. This portfolio is filled with strategies that work with Fixed amount 20$. I tried to calculate the MM in Money Management changing settings with risk 0,2% on account 18.000, that is 36$ about at beginning. Now i think that at beginning it will be open max 2x microlots that open original MM. But is not so. At first trade open 90 microlots against 1 microlots in original MM. Then open sometimes a correct number of microlots and suddenly 96 microlots..... You understand that is impossible that work so.
