The Length of the full midi file imported wrong

Hi

I import the sol.MID in Ableton and Reaper and its duration is 1bar but if i import in synfire the length of the midi file is 4m (4Bar).

In the import midi window i write in Offset: 0m and Length: 1m but this setting does not trim the midi file,is imported with 4m
How can i import the midi file with its original 1m as Ableton and reaper does ?

Cheers

M
