Cannot Edit Traits and Actions

On my NPC template it won't let me edit traits.  Once I hit enter while editing a trait the little gear icon will no longer open the trait for additional edits.  This is also happening with actions.  It was working an hour ago and now it just quit.  Also, something odd, normally when you put in your monsters challenge rating it auto populates the XP.  It quit doing that as well.  Please help.

Sorry forgot to mention this is on the 5e sheet.

Hello Matthew L., Please carefully work through to the first three steps of our guide to Solving Technical Issues : Step 1: Make sure to use the right browser Please check if these issues persist when using both Chrome and Firefox. Step 2: Ensure that there are no extensions/addons interfering with Roll20. Please disable all add-ons/extensions. Step 3: Clear your cache. If none of the above succeeds, please thoroughly work through Step 4. (Don't forget the complete Console Log!) If you need additional information on how to capture a console log we have additional information here: Submitting a Console Log in Firefox Submitting a Console Log in Chrome Thank you! 

Thank you for pointing me to the Solving Technical Issues thread.  Clearing my cache seems to have done the trick.
