Violations appear when plan is published

If I create a plan and publish it, and then another person subscribes to and syncs the plan, that person will see violations. It looks like all the violations related to the last set of changes I made to resources, an example being changing a resource available from 100% to 80%. Why would that cause violations to appear? Also, OmniPlan doesn’t offer any suggestions for clearing the violations. How do I go about clearing these violations?
