Hi Mahlon,
Im seeing the same thing on my test account. I found also that when selecting HTML Editor the entire 'Settings' Section would disappear until I moved the control around on the screen, at which point the settings would show up again, but still display as 'Text Input'.
Ive opened up a new ticket with our development team here to look into the Issue. I will report back with a resolution.
Thanks Mahlon.
