Strengthening Skills

For the last few days the "Past 2" lesson has come up as "Strength: 4/5." I'm "strengthening" this lesson every day, but even when I get perfect results, it won't go gold again. What do I have to do to convince duolingo that I've learned this lesson?

Just ignore the fact that it's not golden and keep learning :) I'm experiencing the same problem with several skills and while it's annoying to not have a completely golden tree.... it's even more annoying to keep strengthening the skills without the strength level increasing
