Ezreal passive ability bug [CLIENT]

When you are in the league of legends client window, open up Ezreal's champion information. Next, navigate to the abilities tab and click on his passive. The last phrase of his passive reads "stacking up to @MaxStacks@ times." This is obviously a bug that hasn't been fixed yet on the client. I would like to see how many stacks he is able to reach in either a numerical form or as a word, but not as "@MaxStacks@" because it is vague and confusing. Also, there is no background photo/video/GIF when you click on his passive ability icon.
