Object Properties Change and Cannot Delete

PixelPie

I am experiencing this with a particular Bryce file.  There arent a huge amount of objects in the file, but they are moved fairly far apart.  This is a radial light I had grouped with some trees while working.. Now I cannot delete it and whenever I click on it, the properties are changed.  I tried changing the properties back and saving the entire file again, then trying to delete the light, however, all it does is revert back to the negative properties and it will not delete.  So I just hid it so as not to have to start all over on this render.  

There were a few trees that I had grouped with this light. I didn't "ungroup" the objects first.. just deleted the tree and forgot about the light. This is the only scenario I could figure that happened and now it thinks it is part of a group still?

Does anyone know what is going on or had this issue?

Difficult to give you a clear answer. It looks, as if the light is an instance and it might be still grouped to an object or an instanced object - is it still linked to an object? From the Object attributes (you show), click on Linking, perhaps you can see something helpful.
