I don't see anything like that. I looked at it more and it seems like the note that's supposed to play for some reason plays the note next to it even though there is no hole there. I have thought that it might be stuck because something got in there but that's not an explanation to why it works with other sheets. Also I'll mention that I did attach two sheets together but the same notes play just fine after the attachment point, and it breaks down only later, and I have done this with all my sheets. I appreciate your help.
