Alignments have to work every time an Imodel updates

We are very glad to use iTwin on our project. Espeacialy to make perpenduclur cross sections from an ORD alignment.

We have experienced that the alignment intelligent disappears, and we can't do cross sections in iTwin. We have a very large Imodel, with a lot of information so we are very dependent of the Imodel in our project.

I have attached a screenshot with the alignments from our Imodel in iTwin, and a screenshot when I have activated perpendicular cross section. All of the alignments should have been active, and they are not. Before the summer holiday the all worked fine.

Can you help us?
