Multiple categories not applying image

Hi, First, thanks for this plugin.
I think I might found a bug.

It seems to work when only 1 category (with the desired featured image) has been applied.
However I have posts where 3 categories are applied. 2 of them have no category image, 1 does. I would like to have that one applied.

When removing 1 of the categories without an image and click apply on the post it works. But applying all 3 categories to a new post it doesn’t.

Have you seen this behaviour before? If necessary I can provide images.

Kind Regards,
Roy
