omsi editor problem: paths over sticky

I had a big problem during I make my map. When I create new splines and crossings, it's always automatically stuck to ending of paths of existing splines. But the problem is that, when I tried to move the crossing to a place with no other object nearby, it still stick onto them even a hundred metre away. So I can't place new roads properly and it drove of crazy. Any idea to tackle the problem? Thanks

Do you have the sound stutting bug and randomly running over passengers too? Please check.

yes i have the knock over passanges one too and now it's even worse that it shows intergeburlauf when I create objects
