Hey Noah 
I can’t really give much advice as I don’t run a support community but I’ve had a gander around meta and found some ideas.
Perhaps make it more obvious to members something needs solving? empty box on unsolved site setting or if you want something a little more fancy, this theme component listed below?
How active is the community and how often do the staff rush in to solve / mark issues as solved? Maybe the users are expecting staff to do the work or a kind of ticketing system (if that any makes sense? 
)
A little reminder that users are more than welcome jump in and help solve other member issues and to mark appropriate answer as solution doesn’t hurt in my opinion.
Interested to hear what others have to say.
