Gifting Center isn't working

Hello,

I've been trying to gift a skin to a friend but unfortunately, when I click on any of the gifting options after selecting their summoner name, nothing would show up. I'm not entirely sure if it's helpful, but I included a link that shows what happens (or doesn't happen haha). Is this happening to anyone else as well? Is there a way to solve this?

Thank you in advance, Emprise

EDIT: I've tried using the gifting center on two different computers (Mac and PC) but the result doesn't differ. I've also relogged/restarted/reopened League but nothing seems to work.
