iMac and Macbook Pro not synching 1Password (SOLVED!)

HI

I have 1password on iMac, iPhone and MacBook Pro.

All have preferences synch settings Primasr Vault to iCloud.

My iMac synchs to my iPhone nicely, but does not synch at all with the macbook. Other apps (such as Notes) do synchronise perfectly between imac and MacBook Pro

Please can someone tell me what I am missing . Thanks
