Try changing the RealTrack to Half Time.
Click on the downward arrow at extreme right of track name in Mixer, or simply R.click track name.
This opens a menu, near the bottom is Track Settings.
Hover mouse over Track Settings to open another menu with Timebase about 2/3 down.
This opens to show Normal, Half Time, etc.
Normal will probably will be selected, so change this to Half Time.

Try this, it often works for me, but your tempos may be too close.
