Need assistance with a tag change?

Question

I edited the question "How to flatten 1/8" Baltic Birch Plywood for laser cutting?" to change the tag from plywood to wood, but afterwords realized I had misread the question. So I attempted to change it back, but stack exchange won't revert since it doesn't detect a change from the original after I revert. It probably doesn't matter since I do not have rep yet for independent edits, but I thought I would let someone senior know in case there is any clean-up required.
