If you don't want any InfoTips at all, ever (which is what it sounds like) it's easiest to turn them off from Preferences / Listers / File Display / Enable file InfoTips rather than one at a time through the FileTypes system.
FWIW I have the same symptom here. even unchecking the "Enable Infotips" option only disables them in Power & Details modes. List, Lg. and Sm. Icons, and Thumbnails always show th infotip.
