Ok so you have used another feature I do not use.
I learned in 2018 that using FLines as baselines was dangerous as it destroyed a whole model file.
That may have changed but as a rule I just don't go there.
It appears the corridor is targeting the featureline correctly but in the shifted coordinates. Not really sure why this would occur, possibly something to do with the programming used for a featureline as baseline.
I'd put this down to a software bug, perhaps make this file avaliable to AutoDesk support so they can confirm if they agree?
To fix, I'm afraid you'll need to amend every affected baseline, remove the target the add back in.
See below, I only did one but it's all good after.

If you are only using for 2d targeting then I'd be tempted to use polylines. In fact' even as 3d I'd use polylines then 3d polylines for level geom as they don't interact with one another.
