iCloud contacts on Mac significantly more than iCloud contacts on iCloud.com

I just spent the night sorting out my contacts and streamlining things so that all my contacts are ONLY on iCloud.

I do not have any other accounts using Contacts - so please - no responses to the effect of "you may have other accounts". That possibility has been eliminated.

I have 3381 iCloud contacts on iCloud.com, and 6523 on my Mac.

I have also removed and/or merged any and all duplicates - a search for duplicates reveals no duplicates.

I am attaching a screen shot so you can see my setup. Nothing is on my 'computer'. The green lines show the iCloud list compared to where those names show up on the list on my computer and there are clearly significantly more names.

I have quit and restarted everything to no avail.

Any idea what's going on?
