contacts not syncing right - phones not agreeing with each other nor zoho contacts

contacts not syncing right - phones not agreeing with each other nor zoho contacts

I had a problem with the updated outlook which I've since corrected. but my contacts on my two phones got all messed up. I deleted all contacts on my phones, made a csv file of my outlook contacts, then wiped out all the contacts on zoho and uploaded the csv file. everything should be working correctly, except it's not.

I'm working between a desktop, laptop, and two cellphones.

zoho contacts, the two computers w outlook all agree that I have 420 contacts
one cellphone says I have 419 contacts and the other cellphone says I have 393.

not sure what to do next... any ideas???
