First of all, only by submitting a ticket you will know what the really issue is.
I would not rely on that list too much. Inno has hard time fixing the DISPLAY of goods used to unlock, try keeping track of actual goods. I have submitted similar error long time ago, and was told it is visual. Then the problem went away, after a while it was there again.... inaccurate listing for minuses is a very old problem.
Still i recommend putting a ticket just for safety, you never know when the problem stops being visual, and starts hitting treasury directly.
