Problem activating section plane

Hi all,

I’ve been using sketchup around 6 months. Everything good.
I’ve encountered an issue in cutting a long section.
My cross section plane works well.

I am left with a blue / black screen on preview / activation of the section plane, espectively.

I was wondering if anyone could assist?

Many thanks

You have section fill turned on. Turn it off in View Menu -> Section Fill.
