Min/Max-Filter on ATR not working

Title basically says all.
Doesn't matter what indicator i use together with the volatiltiy filter, the filter for min/max level on the vola-filter wont work.
I tried different values. 1 / 0.1 / 0.01 etc. If i set a min value trades get opened all the time, when setting a max value no trade gets opened at all.
If any logs or files for debugging are required let me know what's needed.
