Make all active seasons outlined like buttons in the portal

Currently if there is more than one active season, the portal shows the first season circled in blue, like a clickable button. That's great. But the other seasons are just text over the white background. It's unlcear that these are clickable buttons that you can go back and forth to. Many parents asking me why they can't find any class options, and it's because the first season is the "default" the looks like a button, and the second season just looks like text on the page.
