MetaTrader 5 Android bug, create order with lot min and step size of 0,25


Today and earlier days i tried to get a order open on my mobile with the german dax30.

I got the following row:

-2,5 | -0,25 | 1.0 | +0,25 | +2,5

Now if i click on -0,25 i get 0,8, 0,6, 0,4, 0,2, on all of them i cant open a trade.

I do also tried to put in 0,25 over the smartphone keyboard but the second decimal get cutted -.-. There i also cant choose 0,5 atleast. if i but in 0,5 it ends up 0,4.

How to handle this bug/problem.
