Currently in the 'select sources' screen, the entire 'requirements' section of a selected source is either red or black, indicating whether it's valid or not.
It would be nice if only the actual 'issues' with the requirements were highlighted in red, to aid in identifying which source is missing (or added when it shouldn't be).
As a comparison, the requirements for 'classes' are selectively red, so it's clear to identify what else is needed.
I am not able to understand the request in this case.
If you load RSRD for Players and then check on loading 3.5 RSRD Monsters, then the item is selectively red, indicating the portion of the PRExxx that is not being met
Looks like this has already been fixed, it now works as expected.
