Have you ever encountered something like this before? There is not a single bend line.
The interesting thing was that all the lines were there except for one. The arch thing seems active.
I tried many things, finally it was fixed when I made this element passive and then active.
I wanted to share it in case it helps someone.
(you probably all knew this.)
