Legal Question in Civil Litigation in Ohio

Your question has two parts. The "wrong name" is probably not significant and may only be a typo. The decision just gives the judge's reasoning and may not affect the right's of the parties in a monetary sense. The "wrong amount" part could be grounds for the court to reconsider the matter or issue a corrected decision. If the "wrong" committed is a big one and there is legal error on the judge's part, that might be grounds for an appeal. In both parts of your question, the results depend on how "big" the error was and the consequences it has.
