Kontakt Sampler Problems

i’m trying out kontakt 2 sampler but i have a weird problem.

When im in DFD mode then its OK, but as soon as i switch to “sampler”, “time machine”, “beat machine” etc modes then kontakt inserts some weird “tail” to the end of the sample. The sample gets little longer and the start/stop markers are wrong!!

Are anybody having same problems? or is it just me
