[Bug] A "lingqed" sentence is returned back to blue

I was busy with reading the 6th lesson of the Japanese Greetings and Goodbyes course, and I had all blue words “lingqed”. I even had some sentences turned into “lingqs”.

However, after closing the lesson and returning to the library, I noticed that the overview stated that there were still 2 more words to “lingq”. Strange because I had all words “lingqed”.

Here is the link to the lesson: Login - LingQ

Some screenshots with an example within the lesson. The first screenshot shows the sentence (which is not even properly parsed as the individual words can’t even be selected), and the second screenshot shows that the sentence is present in the vocab list but the entire sentence remains blue.

Can this be checked please?

Thanks for reporting, we will investigate the issue.
