Copy/paste only on the track where the rushes were

Hello,

Since the last update I have a problem with copy / paste.
Before when I cut a rush, I selected a track, V2 and A2 for example, and I pasted that above my interview in V1 A1.
Carefree.
Now when I paste the rush it automatically goes to V1 if it was on V1, V2 if it was on V2 and so on.
And it's really not practical, I either have to lock the V1 and A1 tracks, which forces Premiere to stick on the track above,
but I don't like to lock the tracks because you can forget one and after there is problems with the audio.
Or put the illustration plans on the V2 and A2 directly upstream, not practical because I only use 2 tracks.
It becomes painful when you have several tracks, you have to shift what's behind, paste, 
distribute on the tracks you want and then drag the rush and the audio to the right location.

Is there a checkbox that got disabled?
Honestly, it sucks, I have a project that's a bit long to set up and I don't need that extra to waste a lot of time...

Thank you,
Seb
