Default Duplicate showing in query when there shouldn't be

You have what is known as a Cartesian effect. This happens when your tables
are not properly joined. The quanity of records in one is multipled by the
number of records in the other.

Post the SQL of your query for suggestions on how to fix.

Hi,
So new to this I could pull my hair out. So go easy on me. Thank you for any
help you can offer.
I have 1 query that is pulling from 3 tables. In those tables there aren't
any duplicate entry's yet in the query i get duplicates for some entries. I
can find no correlation as to why it could be choosing these as duplicates.
Any direction?
