Why don't you get xp points sometimes? I wrote this translation correctly but got no points

put kid instead of boy, didnt work

In the drop-down it says that læser is 'reads', 'studies' or 'is reading'. 'The boy is studying' was marked wrong and corrected to 'The boy studies'. Why is the progressive form accepted for 'read' but not for 'study'?

I seems to be stuck and going a loop despite correct answers
