How do I remove red dots created by topology checker?

I was trying to check for overlapping lines within one layer by using the topology checker --> Must not have Dangles. This didn't work, I'm trying a solution posted in

However, I'm still stuck with the Red dots that the Topology checker provided. I removed the rules and turned the plugin Topology checker off, but the red dots still appear. Even unchecking all my layers doesn't work. It's probably an easy fix, but I don't know how.

In the picture one layer is still visible, but turning it off doesn't remove the dots.

    If you un-check the show errors box do they still appear? If you run the topology checker using a tool or extent that will not produce an error, does that remove the red dots? This usually works best if done as part of the same "session". If these don't work I'd close the project and re-open it.

To get rid of the red markers that show topology errors, uncheck the box at the bottom of the Topology checker panel that says show errors:
