Could you please provide more information about this issue? At least it would be good to know where this issue appeared, on which page and with which display size
I think it's the same problem as in Hjelp. This occurrence is in the students overview. In general, the problem occurs on all icons with <icon>_circle.
I found the problem, it is actually something different. Our currently used icon library allows to include icons per classname. In the situation the icon has the class circle that makes it this green circle, but includes a circe icon as well. This is because there is a conflict between icon class circle and the materialize class circle. We now either have to change this scss code to don't use icons per css classes or this line, to have a prefix for icon css classes. This means compiling scss locally. A dirty but quick fix would be to create a css class that simply removes all :before content of an <i>.
