Analyzing resources and roles, tickboxes grayed out
I have had P6 Professional release 17.12.1 installed (standalone). I have just noticed that when analyzing resources and roles, that 'Display activities for selected time period' or 'display activities for selected resource' tickboxes are both grayed out. There are roles and resources loaded on the project. This applies to any project I open. Has anyone else encountered this, and what's causing it? I don't remember having this issue on my previous V15.
