MIDI Pickup Measure Detect Shows 8/4 Measure Instead of Pickup Followed by 4/4 Bar

I imported a MIDI file (attached) to test some of MuseScore 2.0's new MIDI features. I noticed that MuseScore did not properly detect a pick-up measure. The original score to the piece shows the first measure is in 4/4 with a quarter note pickup; however, MuseScore showed it as an 8/4 measure with three beats of rest at the beginning.

I am running MuseScore Nightly 75d9e76 revision on Windows 7.
