I don't know of an automatic clean-up process.
What does "Properties" say? Maybe radius = 0? Linetype = No Pen?
Does "Select All" and "Auto Zoom" show the associated arc?
What kind of deletion does work?
Maybe you can delete everything else, so isolate that entity and save as an extra file. If you provide that file maybe someone finds out what's wrong.
