Feedrate decreasing during printing M201

During printing the feedrate (showing on the LCD) continuously decreasing. Around 30mm height the feed rate decreased to 36% from 100%.
I guess it is not normal, the printing speed was very slow of course. Should I change any settings to avoid this?

I did not checked in case of printing via USB, but it occurs every time I print from SD.
It seems the feedrate decreasing in function of z height.

Weird...You can try printing via USB and see how it works.
