taking wrong runes into game

ive had a couple games where i take the rong runes into game even tho i changed the page to what i wanted. i think it happens when you edit the page in champ select and save (say page 1) then the next game if u choose a page without editting (page 2) the game still takes page one even though i selected page 2, but if i edit page 2 and save it takes page 2
