OP knew what the code meant. He, in fact, brought it to TSA's attention. TSA failed to "clear" the code and nothing short of a lengthy explanation on a smallish piece of paper would have solved the issue, e.g. "even if a TSA Officer tells you otherwise, you need to have your BP properly stamped before you will be permitted to board."
TSA screwed this one up. End of story.
Hopefully the Mods will move this out of the UA forum as it has zippo to do with UA.
