Messy track layout in the mixer.

I’m working with a really arranged layout as a template for Post audio.
On my last template, I made some changes and noticed a really strange behavior of Nuendo messing up.
In the editor view, all the tracks are laying in order perfectly as I build it but when going to the mixing screen the tracks are all over the place.
also when going to SENDS list.

I added some pics to give the full idea of the problem.

what do I do wrong?

Try saving and reloading and see if that helps.
