Invalid fades on playlist "?"

[audiot]

When I open a PT LE 8 session suddenly following error is reported:

Fade out "Fade CS0vg87PlwSk" at 5:34.875 on playlist "?" is invalid because its left contributor is a fade.
Fade out "Fade pS0vg87PlwSk" at 5:34.875 on playlist "?" is invalid because its left contributor is a fade.

I´ve been working with this session for weeks, without any error!
Suddenly the error appeared out of the blue!
I did´t work in that time area at all!
There is no Fade at this timecode!

I know this issue since PT 7.x
Now we are on Version 8. --------> still unsolved!

This is not the first thread for this problem.

DIGI keeps quiet about it.

So DIGI. What is that? And how can we get rid of it?
Working on large projects really needs confidence in the software we´re using.
You owe us an answer!
