How can I delete those grey circles
Even If I choose to show my logo https://www.google.ca/?gfe_rd=cr&ei=mikaV7nyCevK8gfI7q6IDQ#q=simplicit+marketing it still show that deleted pictures??
Re: deleted photos
These are usually placeholder images that show up when other images are deleted from your listing. It usually takes about 24 hours for them to disappear, and in your case I can't see them at all any more.
If you're still seeing them though can you please try clearing your cache to see if that helps. If not, please contact GMB support at https://support.google.com/business/contactflow to ask for assistance in removing the placeholder images.
