Hi zosont,
Could you email your OmniPlan document to
omniplan@omnigroup.com for us to take a look?
If there's confidential information in your OmniPlan document that you don't want to share, you can go to "Help" --> " Send Feedback" in the menu bar and click on the "Include..." button. This will create a randomized version of your OmniPlan project where the task and resource names are replaced with generic names.
