[RAPPS] does not seem to refresh the installed applications view when pressing F5

I installed Opera 12.18 via rapps. And left rapps running the whole time during that test
When I finished the testing I tried to uninstall it via rapps.
It was not visible when I clicked the "installed applications" in the rapps treeview.

Expected result
It should be visible, especially after pressing F5 in there

Observed result
Even after pressing F5 the view did not show Opera 12.18.
Only closing and reopening rapps made it visible for me.
