no resets reviewed words in Lesson Practices

[louis.vang]

I have spent some time with English > French and French >English.
That was the reason that 24 skills of English > German were no longer gold.

Today I liked to update the 24 skills via Lesson Practice.
I did several times the Lesson Practice, some times with only 18 or 19 correct answers and had to start again.

Many sentences that I had correctly answered I got back in the next Lesson Practices, up to five times, which Duolingo referring that some words were not seen already a month or a week.
But I had used this words many times in correct sentences.

Duolingo didn't set all this words to " recent seen ", after inserting correct sentences.

Is it possible that the reviewed words in the 18 correct answers from the twenty are not reset to " words practiced " ?.

After tens correct answers i have still 24 skills 'no gold' , because i get always the same sentences to translate.

Greatings,

Louis
