Spaced repetition does not refresh correctly

Spaced repetition

Duolingo's algorithms figure out when you should practice words to get them into your long-term memory.

First of all: you are doing great!
Keep up the good work.

I noticed by accident that the algorithm does not always update the 'Last practiced' field.
For example: lee . This word was in my last 'strenghten the skills' exercise. It still shows the value '1 month ago', but strenghts of words practiced is correctly updated.

I want to emphasize that you are doing nice work and i really appreciate your website!

If you need any help in solving this problem i am willing to help you.
