Boss Extrude not updating

Hi There,

I've had to draw a heap of washers, and I'm bunny hopping off the original drawing and just changing the external OD. I'm into my 12th washer and the Boss extrude hasn't updated?!? the SLDPRT I've attached has a 299mm OD in the sketch and 297mm OD in the Boss.

So when I saved the DXF's for cutting, it's reading the 297mm Boss Extrude dimension.

Why isn't it updating?

This isn't the first time this has happened? is it a glitch? or do I need to tick a box somewhere on my option folder?

Thankyou in advance.
