Reply to beatgridding problems with traktor pro

ive been using traktor pro s4 for a while but just installed traktor pro 2 on my laptop since thats the direction they are heading and ive noticed the beatgridding is far less accurate on this. is there a reason for this? ive had almost no problems with the auto grid when using the s4 version but noticed that i have to adjust almost every song in traktor pro 2
