I could be completely wrong here, but, I think that this has been covered in detail either on this forum or another English speaking forum. I think that a small section/area needs trimming off - that is all I've remembered. Maybe try Google!
Yes it has been covered a few times now (by me) lol if you want I will get a pic of the bit that needs trimming when I get home tonight? It is easy enough to do with a dremmel or a sharp knife if you don't have a dremmel and you are careful.
Can you post the pictures up on this thread please SI-W85?
