Hi Mahlon,
Thanks for bringing this to our attention. It looks like when you only change the case of the Name, an update to the FullName field is not being triggered. I have created a ticket for the development team to investigate and will post back once this is resolved.
In the mean time, you can force it to update by adding any character to the end of the name, saving, then removing the character and saving again. As long as the spelling changes, an update will be triggered on the FullName field.
I hope this helps.
