Having traffic lights does not stop these junctions being roundabouts. The signposts approaching them use roundabout symbols. If the traffic lights are not working they would be navigated as roundabouts. Also many of them didn't always have traffic lights when built and were roundabouts then. Adding traffic lights to a roundabout doesn't stop it being a roundabout.

These junctions were tagged as roundabouts in the past. 

Changing roundabouts to circular junctions just because they have traffic lights is not a good idea.

In the UK a circular is a rare type of junction. Some do exist.
