Could you be more specific? Which are you using, MZ or MV? Do they match the generator parts you're putting them into?

I don't know if this will help, but when I was going through the files I saw that in MZ's TV folder both of the male files for the replacement titled "TV_Body_po1" and "TV_Body_po1_c" were similar if not the same? Then again, I just took a glance after I noticed something was wrong with my own set up.
