Magnetic layer detail option grayed out

Hi there,

Im trying to change the detail of a magnetic layer and the option is grayed out under layer attributes. I tried to select and deselect and click on the magnetic tool again but it’s still grayed out.
Any idea why?

Thanks in advance

You can take the detail down immediately after the shape is made, but if you alter the shape in any way before that, it locks taking detail down.

I just figured it out haha
Thank you for the quick reply, trying to get to know the software as quick as I can.
