Playback slows down and get out of rythm. MIDI translation is not optimized

Musescore 2.0.2 on Windows 10 and Lenovo Yoga 15 with 16GB RAM and Intel I7.

When I playback a score imported from MIDI it slows down in some points. I have used the same midi on Notation Composer without any issue. No other application is running on the PC.
I have found out that MuseScore, when importing, it splits the melody on two different voices even if there is only one.
It is very annoying because one cannot use it to learn a song...

I attach the file.

Kind regards

MuseScore split the song into multiple voices because the original MIDI file most likely contains overalpping notes. There is no way to represent this without either using multiple voices or lots of ties. You can force the latter by changing the maximum number of voices to 1 in the MIDI import window, but the result will be even harder to read. Better to clean up the MIDI file by removing the overlaps. Assuming you produced this in some sort of sequencer, use the quantizing function to straighten that out.

As for the slowing down, I don't hear it. Can you point to a specific place in the song, where you think the tempo is not correct?

And as mentioned, please attach the MIDI file itself.
