Facing an issue regularly while opening assembly file showing outdated component/feature.

Facing an issue regularly while opening assembly file showing outdated component/feature. For now, I found only one way replace the each component, where there are more number of components to see the task what before day did. Took time to achieve the assembly that was in progress for last day, time completed to start from there. Someone find this issue and give a suggestion for this. And I'm using educational version creo.11.0
