Official transcripts "Do not use"

I was informed to send in my official transcripts to a school by a certain date, and next to one of the schools I attended it says "[name of school] - “DO NOT USE” it’s the only school on the list of all the schools I need to send in transcripts for that says that.
Can anyone tell me what this means or have any guesses? I’m going to contact the school and ask, but just wondering if anyone has seen this before or has an idea.

I haven’t a clue.

I have no clue either.
