@talbs @gwprice would you mind reviewing this and providing any comments when you can for these fixes? I've run into development environment issues and wanted to get this out there as soon as I could to give more time for review. I did test this on one of the input fields and verified it work, then replicated the same modification throughout the other instances of the issues. I'm fairly confident further testing wouldn't yield any surprises, but I added the DO NOT MERGE label since I didn't actually get a chance to fully test it.
