Having an issue with the button fixings, For a fixed panel on a cabinet it works as intended

When I add it to another panel on a product, it comes in on the front instead of the back. No issue, I just -10.5 or whatever I need to do, then for some reason the PLINE machining moves to the left by 15mm from the hardware block & drilling. I've tried copying the hardware, renaming it, creating a new DWG & adjusting the PLINES over 15mm, adding the hardware to the sub back instead of the facia panel, looked through any lookup table nothing seems to work. Any ideas?
(Blue is the panel, white is the block/drillings)
