Mismatch between right column information and graph

[Preben Aas]

Many courses display different value between the written information and in the graph (course specific graph). E.g. "ganske bra" (in text form) shows up as almost "Særdeles bra" at the graph.

I suggest to remove previous semesters at the newest KK (v2017) and start fresh.
