Lesson skipped some steps

[pauldev]

I was progressing with Plurals, having finished the first lesson, and the next lesson to come up was not Plurals, but was Possessives.
What happened and how do I get back to Plurals>

Same here. Every day I get a reminder Today’s goal: Master the skill Plurals, ....You’re only 2 lessons away...
However only 1 lesson is offered! And my Spanish Skill tree says: You finished this skill!
