I needed this plugin for post category "Koulutukset" ...in sidebar widget it is also called "Seuraavat koulutukset". Fine. Just as it should be.
But then I have another post category collected in separate page called "Ajankohtaista" and its listing looks great. There should NOT be any custom field values in this category.
Problem is when you choose single category post from this "Ajankohtaista", check this out! It has all extra field values from "Koulutukset" category!!!!!??
I have my options set up as I saw someone here solved the problem. It doesn't help:
Show this field group if - Post category - is equal to - Koulutukset
