1) The titles you have pointed have a style preset attached (Title separator). The preset can be changed from Theme Settings > Style > Presets > Title separator > Colors. However you need to apply a patch first as there is a problem at that moment that prevents the saving of built-in presets. We’ve attached an archive to extract in your store’s root folder.
2) Have you removed these categories from Admin > Catalog > Categories? Maybe you need to rebuild categories.
