icloud contact sync issue

Dear community,

I've imported my gmail contact to icloud through an gmail export / icloud contact website import and I'm having very strange issues.

600 contacts over 700 were imported and that's fine but I got many duplication on the icloud contact website whereas on my iphone it is missing many including no picture sync for some and on my mac everything is perfect!

I have been waiting for two days to see but no change... It seems a strange cloud sync engine issue and I have no idea on how to solve that one.

Thanks for your help.
