Image slider navigation arrow positioning problem

so i've been tweaking my website here and there and i must of changed something by accident because now my right-arrow on the image slider is not positioned correctly..

i dont understand what it was because i didn't touch any of the css/html coding for the slider..

also strangely enough, if u resize the browser then return to fullscreen, it is positioned correctly. Puzzled


anyone know how to get it back to the edge of the photo?
