Hello Abhi, What most likely occurred was that a transcript mapped nearly identically to multiple locations. This has several possible biological causes that vary from case to case. You can read more about the methods used for mapping in the track description.
I hope this clears the issue up. Please feel welcome to contact us again with further inquiries.
