Roland FR7XB Midi problem

[dagaanes]

Enybody have a suggestion regarding my midi problems.
When connecting the FR7XB to BK-7m the right hand keyboard is falling out the same time i move the bellow.
I am using the wizzard connection on the BK-7m, and tried Accordion 1 and 2 but the same thing happen every time.
Suggestion please

Not sure what you mean when you say "falling" out. Does it work properly for a time and then fail or does it fail from the first moment?

A video may make it easier to understand/see.

I will try to make a small video when the accordion return from repair at my son in law. It may taket some time but i will try to remember do so at the time I have the accordion.
