Inconsistent word strength
I noticed a strange thing:
When I sort my vocabulary by word strengh in ascending order, the first words have full bars:
I opened one of these words to see the strength of its forms, and here's what I see: http://i.imgur.com/EbmmjO7.png
All the word forms have full strength, but the word itself has only one bar.
Does it mean I still have to practice the infinitive or is it a bug?
