I've got the problem that a lot of my products have the status 'not controlled by WC' and then they give a - in the stock selling manager list. What causes me to not be a able to see the status (which works well for me).
I've tried marking them and to activate them to be controlled by WC. But it doesn't change the status to green orange or red. It just stays -
I've also compared some product settings to see if I could find a difference, but I can't find any.
What am I doing wrong?
