Can't delete the very bottom Dynamic Field in World Editor

When in World Editor editing an object, I can't delete the last Dynamic Field in the Dynamic Field list. When I click on the minus sign, it just scrolls up the inspector window and does not remove that last field. The others will remove fine but that last one is a pain! I am using the binary download of Torque 3D and I have uninstalled and re-downloaded and re-installed and that does not fix the problem. I was editing the PlayerStartSphere in the FPS Example in the blank level, trying to remove the lock attribute in Dynamic Fields. It is the last one listed.

I am using Windows 10 if that makes a difference. Everything else seems to work ok.

This is not stopping me from working with the editor, just an annoyance that I discovered. I was able to script that object and do whatever I wanted to with it anyway without removing the lock attribute.
