Using Brother chunky with ribber and Knit Leader

When I try to use the long brackets that come with the machine to use with the Knit Leader, they hit the table due to angle of the machine with the ribber attached. I wondered if anyone has solved this problem? Unless the Knit Leader sits properly, the two trippers on the carriage don’t hit. Only one does, so the knitted piece is twice as long as it should be. Any suggestions would be truly helpful. Looking forward to the Bournemouth show, only a few miles from me, which is lovely. Thank you for any help. Kind regards, Jean
