The table name being generated is a join table. At least, I have to assume that, because you didn't include the code that generates this query.
You probably are intending to use ITFKs, but you have them mis-named. If DMZ doesn't see the ITFK name on the table, it assumes there is a dedicated join table. The reason the table name appears twice is DMZ always adds an alias to the table name, to allow for advanced and deep queries.
Your problems are most likely stemming from the fact that your model names and table names are very different. While it is possible to do this with DMZ, the ability to use a different $table name than the generated one is specifically for helping with unusual pluralizations, not for complete renames. The way you are using it is not supported, so I can't help you figure out your problem further.
