Deleting an Invisible/Empty Dynamic Shape

Hi All,

I've managed to create a very small dynamic shape in my deisgn (a 200um circle). It doesn't fill, and I don't seem to be able to reach it with any tool. The only way I have to see it is to edit the boundary of another shape.

Because the shape is empty it is flagged as out of date by the DRC.

Any suggestions on how I might go about deleting it from the design?

I'm using 17.4 S008 for reference.

Thanks!
