LineColor Node???

This is a strange one.
In Fusion, when I either click on Background to add a background node OR manually add it, the node that is added is called LineColor. If you search, you will not find a tool called LineColor.
I rebooted. Same thing.
I tried various other projects. Same thing.
It is totally bizarre!!
When the LineColor node is added, the background it White. See attached.
Any ideas on what happened and what are the next steps?
