I see what you are referring to but I would cut the butplate off and reshape the end of the stock and BP to a pleasing contour and not worry about it, looks good as is.
You have been given some really good advice here. Now to put in my 2 cents worth. My mentor on my first build (all hand tools electricity hadn't been invented yet) told me when I come to a problem to hang the rifle on the wall and come back later and look at it, the next day cut the grass and come back and look at the rifle, the next day wash the car and come back and look at the rifle. By giving yourself some time to look at it you will see different things and have a better idea of what needs to be done, or else you will have everything else done and have nothing else to do but work on the rifle
