Lloyd,

If it is a 545i as opposed to a 545 then it may be the bulbous nature of 
the business end holding the holder slightly above the film plane and 
allowing the light in. I have had similar problems trying to use a 545i 
with an MPP Technical camera - luckily managed to spot the problems before 
exposing any film..... The older all metal 545 holders work perfectly.

Cheers,
