Roll button & sampler

Since upgrading the Serato i have had lots of issues with my SR.

Frezzing has been one which i have upgraded the firm ware to 1.7 but the ROLL buttons now are synced with my sampler?
when i switch on the controller the roll buttons are sampling 4 and 8 bars, if i adjust the sampler it adjusted the sampler when using the hot cues?

Any ideas?
(hope that makes sense)
