Q: Thunderbolt Display Firmware Update 1.2

I have a MacBook Pro (Retina, 15-inch, Mid 2014) and two thunderbolt displays. I recently started getting notified there was an update available, Thunderbolt Display Firmware Update 1.2 and App Store kept prompting me to download and install.

 

I tried multiple times, and each time it states it failed to update. According to this KB article About Thunderbolt Display Firmware Update 1.2 - Apple Support it states Firmware Version should be 26.2 and the Port Micro Firmware Version should be 2.0.7 after the update.

 

I checked and my Mac is in fact reporting the updates were applied. See information from the system report below. I am prompted every day, multiple times to download and apply this update again, over and over. I don't understand why.

 

I contacted Apple Support and the rep I worked with was pretty much useless. In fact, I am fairly sure I know more and *NIX than he does. Anyway, does anyone have a suggestion on howe to remedy this?
