First Win of the Day

Dear RIOT,

I'm frequently noticing that my Profile page will show that 'First Win of the Day' is available, when in fact I had a First win a few hours before. Refreshing my profile doesn't work. However, if I log out, and log back in it'll show that it is hours away from having a first win of the day again. This only seems to occur in the legacy client though. The Alpha Client, although it being somewhat obscure to find 'First win of the day', does show it correctly though.
