How do I get rid of linked tracks?

In my recent project, Nuendo 6.0.2 is linking imported tracks at random it seems. What is this function and how can I get rid of it? I’d be very thankful for an quick answer, this is really disturbing… :angry:

Project or mixer window? For project if they’re in a folder check you don’t have grouped folder editing enabled. If they’re grouping at the event level then you can ungroup them. For mixer check to see they’re not part of a linked fader group.
