Hi all. 

I've spoken to EA support via chat and they acknowledge the issue, and asked me to repost it here.

Like every week I have redeemed entry via the companion app (yesterday in this case), as I rarely play during the week. 

I just got on the console and suddenly all the points are back in my account and I can only register for next week. I'm a 1000% certain I successfully redeemed entry yesterday. All fun and games but this is the most profitable Weekend League of the year so this is a real shocker. 
Please EA, HELP?!
