Cross Member issue in RM Bridge

I want to create the hangers for an tied arch bridge. I use cross memeber to create them by connecting segment point on the arch and the tie.

PS. It seems that the forum doesn't allow uploading the media (picture, video) from my computer, I have to upload it to other web site, then use the URL.

When I run "Recalculate Modeller" in Modeler, it shows

Geometrical position of segment "Hanger in P1 1" not OK
Check segment points and connection points the cross member is connected to.

When I run "Recalculate Analyzer" in Analyzer, it shows

ERROR: Element 3101 has zero resp. neg.length

But it shows correct location in the GUI
