On topic Numbers and quantities:

Therefore the course "Decimal fractions" has to be removed from "Numbers and quantities" because there are two topics "Basic arithmetic operations" and "Decimal fractions" both beeing child of "Numbers and quantities".

I suggest: Dissociate the course "Decimal fractions" from "Numbers and quanities" and associate it with "Decimal fractions" (https://en.serlo.education/41051).
