I have configured Webwork 2.17 in our test instance. When I go to Library Browser > Local Problems drop-down, I see webwork-open-problem-library problems (as shown in the screenshot below). I got to know from a user who is currently using 2.15 version that these problems should not be visible here.
I tried deleting the webwork-open-problem-library directory in /opt/webwork/libraries/ but that did not help.
How can I fix this?
