Short edges after solid subtraction

When I subtract one solid from another when curves are involved SketchUp creates short edges (Clearly a fault) how do you get rid of them. I cannot do any other solid work with the model until they are eliminated. I have tried scaling up and down without success

Could you share an example so we can see what you’re talking about?
