have you tried refreshing your web browser or it might be lag or a delay there is many things but it also can be a bug.
This is WAD (Working As Designed).
It tells you the total gems you have recieved from the level, not how many you just received this time around.
Normally, Iād tell you to search before posting, but sometimes it might be hard to figure out exactly what to search forā¦ Oh, that wasnāt so hard after all, so Please search before posting. 
I searched on āgemsā and one was on the first list.
