I am having the exact same problem.

I never really dealt with tournament items before. I traded for a tourney drodo, and after right clicking it, I noticed there's an option to remove the description tag. Upon seeing that option, I thought the tourney drodo I traded for had a fake description tag attached to it, so I removed the description from it. I noticed the match id# is still on the drodo, so turns out it was a legit tourney item after all. Is there any update as to whether or not Valve will replenish the original description tag? I feel borderline cheated. Why is there even an option to remove the tournament description from it in the first place?
