Senna bug in shop, she does not appear when classes are checked

I was in the champion shop today Senna is in the shop but when the check boxes are clicked she does not seem to appear in any of her appropriate boxes she doesn't appear when marksman and support are both checked and does not appear when they are individually checked either I do not believe she appears when any boxes or combinations are checked she only appears when none of the boxes are checked I know this is probably not a bug, and riot maybe forgetting to make her appear if the boxes are checked but this is the most appropriate section to post this in
