Steps to Reproduce
Go to Platform Monitor page
From Tools Menu drop down ,select New Auto Discovery
Click on any three buttons(Ok,Reset,Cancel)
None of the buttons works
Lowering severity as there is a work around.
Though the buttons do not work at the bottom of the page, the top buttons under Quick Auto-Discovery Scan do work. The settings within the Extended Filesystem Scan Configuration can still be configured and using the top buttons will properly accept the values.
