Hi to everyone

I have a project that migrated to S7. I uploaded a backup and I want to edit one of the FC in this project. After editing some of the networks I could not save the FC. I have no the old project (S5). One of the networks have been an error and I uploaded a photo of this network. I think that network doesn't allow to save the FC after edit.

Please help me to fix it.
