5 hour achievement not showing? [已解决]

hello, I'm new and I have been practicing on LoA a bit more and more, I was looking forward to receiving a 5-hour achievement, but I haven't gotten on yet.

I got a 2-hour achievement a few weeks ago and I have been practicing for a few days, it even says for this week I have practiced 3hr and 20 minutes, if my math adds up then that is at a minimum 5 hr 20m?

thanks!

Update: I got the 5 hour achievement and the 10 hour achievement at the same time, i think the 5 hour badge came a little late, don't know why, i just did an 1hr 30mins session, so i couldn't have collected both at once
