I thought I understood Finnair’s fare classes, but maybe I don’t.

I had some flights that I thought were Value fares that should earn 100% but they have credited at 50%. I went back and checked, and it looks like I booked a “standard” class ticket. Is “standard” not value? The fare bases for the flights are QLN7T7M5 and NKX8F7M5.

I am assuming that a ticket with fare basis ZVA2FI is a Value fare. Thanks in advance for the clarifications.
