Pages are not updating in Citect 2018 Update 15.

Is the backup from 2018, or an earlier version?
Is the backup being combined with projects already on the other computer?
When you say "not displaying correctly" what do you mean?

If Save is resolving the issue, then that means the Update Pages believes there are no changes and so it skips the save process. Manually saving forces the save process. Obviously you can work around this, by saving every page manually, but it would be good to understand more to narrow down why citect believes your pages are up-to-date.
