I was placing an apiary when I noticed something about the bonus. It looks like the ‘layer’ doesn’t get updated when you move or relocate buildings that apply a malus (you can see the dark spots on the map from where I had previously placed buildings).
The pictured apiaries were built after I moved the buildings that imposed the apparent penalty, btw.
Also, it looks like gardens and other decorations no longer provide any bonus. I don’t recall seeing that in the change logs, so I thought I’d mention it in case it’s unintentional.
