Extra spacing when using native bulleted list

I have identified an issue with Rise where extra spacing is assigned to the last bullet of an unordered list <ul>, creating a visible gap on both desktop and mobile.But it is made more apparent on mobile as the gap creates a white background also, this is evident when the blocks have background colours assigned. 

it appears to be within the <ul> tag and margin-block property. 

Is anyone aware of this issue and is there a workaround?

Thanks very much
