ProjectLink Editing

All -

I have a user building a ProjectLink project, and he is unable to edit the date information for some of the tasks. We have a template that separates the project into 5 phases - he is able to edit for phases 4 and 5, but not 3. Any ideas why that might be?

Windchill 10.1, M040

Thanks in advance -
