Post Page Grid- Missing params when Pages selected

If I create a ‘Post Page Grid’ for posts, I have controls in the right hand bar to edit the number of columns, number of items and items to offset. However, if I swap to a Pages selection, these fields dissapear, but they still take affect.

Thus if I add many pages, the display will be limited by the now hidden ‘number of items’ field. I have to switch to Posts filter to change number of items, then switch back to Pages.
Similarly if I want to change the number of columns Pages are shown in.

Granted I can use the above method as a workaround, but it’s a little annoying
