Skill not strengthening

I've got one skill that went down to 75 percent in my Spanish tree and I have now practiced it somewhere around 5 times now and it still won't strengthen...

I've noticed it seems to be based mainly on how many lessons a particular skill has. So some will level up after a single practice, some will take 5 or more...also sometimes duome doesn't sync properly but will update later on. Maybe take a break for an hour or so then check back and practice a bit more if necessary.

this was last night. I did finally give and and came back just now did it again and it still didn't strength frustrating because it is such an easy lesson. Each time I've done it I've either gotten perfect or made one typo and missed one question. It wouldn't be a big deal but my OCD wants everything gold

Sometimes the skill strengtens only after practicing it or doing new lesson around 10 times. I got used to it. Keep repeating, it is going to strenghen finally.

I have at times had to do it two or three times but 10? really?

It seems that I got punished for my comment, because now I have the same issue with my Spanish course. Stuck on 75% strength in several skills and they won't increase no matter what I do. What's more, the individual words that I surely trained dozens of times lately show as last trained three months ago and have only one bar of strength. Reported it as a bug one week ago and still got no reply from Duo...

I'm having the same issue with a lesson in my French tree -- I've practiced it many, many times over the course of the past week and it's still stuck at 75%.

I'm having the same problem with my Spanish tree from German. About 3 weeks ago Basics 1 and Ser/estar dropped down to 75%. I proceeded to get both up to level 5 so I could do the strengthenings, but it made no difference. Now Basics 2 and Plurals have joined the other two skills as permanently showing 75%, no matter how many strengthenings I do. It must be a glitch, as these skills are so basic! And I've now done many strengthenings without making a single mistake.
