I am getting message: "Free Margin should be around : XXXX"

I'm having problems with the words "Free Margin should be around : XXXX" at the top left corner of my mt4, it doesn't appear in my other FreeMargin_for_AutoLots size, it only occurs when I'm having decimal figures ... others used are 0.1 /0.2/2/5/10 only the 0.1 and 0.2 figures in the free margin for autolot encounters problems...

for eg. on forex.com if FreeMargin_for_AutoLots=0.2 then you may get message "Free Margin should be around : $7187"
Reason for asking $7187 [atleast]
Forex.com requires approx $14.3 to open its minimum lots size(0.01) on 1:100 leverage. So if you want to set FreeMargin_for_AutoLots=0.2 then you must have $7187 [because 0.2% of $7187 is $14.3]
 
So if you set 0.1 for this parameter you will get the mesage for $7187 X 2=$14300,
and similary if FreeMargin_for_AutoLots=1 then $1430,
or if FreeMargin_for_AutoLots=2 then $718, ..............
 
Now in any case if you have $1000 in your free margin, so it will try to open lots size which covers in 0.2% of $1000 = $2  and which is impossible as there is requirement atleast ~$14.3 with forex.com. So in this case it will open the smallest lots size which it can open, i.e. 0.01.
