Only new words appear

Today I had a sequence of about 30 new words without any interruption. This had never happened before, so I stopped the usage to make sure this isn't a big.
Can this please be checked? My words to repeat seems to be stuck at 50.
I am learning French from English using the Android app.
Thanks a lot.

This happened to me today as well, almost 150 new words in a row in German.

Today I opened the App, and the bug seemed to go away. This issue can be closed, thank you.
