Acheivements not showing last threshhold

I have been receiving an achievement notice with every 1000 new words known, until now. I am at 8012 words known, and it is still showing my last achievement as 7000. I have checked on every device I own, and it won’t budge. Are we not getting these achievements anymore?

Hi Kate,
Please make sure to complete a lesson, and as soon as achievement popup appears on your screen, notification should appear on your profile too.
