Serato DJ Pro beat grid integration on ENGINE Prime

Hi,

Now with the MCX8000 V2.0 i’m using ENGINE Prime for prep my USB Sticks. Before I beat grid my tracks with Serato DJ Pro but when i import them on ENGINE Prime 1.1.1 a lot of them have incorrect beat grid and BPM. Anyone have a answer for this?

Thx

In what way are the beatgrids different ?
