I'm sure they won't publish a correction.
Note that the spec says to find a 3-digit number which satisfies the criteria, not the 3-digit number. That there are multiple such numbers, and you could've found a different one, doesn't violate the spec.
Once you've done what it says, you will have 3 3-digit numbers, plus their reverses. That's 6 integers.
Yes, other people could validly come up with a different set of 6 integers. So what? There's nothing in the spec prohibiting that! As others have noted, all that matters is the smallest and largest integers in that set — and all the possible sets of valid 6 integers have the same smallest and largest.
So, following their instructions does yield 6 integers. And the answer to the question they asked is unique.

Having worked on interesting puzzles like this as long as I can remember, as well as knowing many people who have the same interest - this is the type of puzzle no one likes to work on.
A simple foot note that says: While multiple preliminary solutions are possible, the max and min will always be the same.
Would have gone a long way to making others and myself happier that our solutions were correct.
By the way - you have read into the spec.

They're not usually this unclear. I think it's just a fluke, but I'd have to work through some others to be sure.
