V11d windows.

I have a selection list that says backup 'servera' folders x, y, z

That runs fine for a while.

Then one day, it starts backing up serverb instead. If that server does not have folder y, the job fails.

I look at the selection list and it looks fine - servera is listed.
But on the 2nd tab - selection order - it lists serverb instead.

When I re-create the selections, this solves the problem.
Until the next time, it keeps coming back to haunt me, I keep having to re-create the list.

What might be happening?

Known bug ?
Name resolution problem (not that I can find so far) ?

thx
