Contacts not visible Opportunities

Hi all,

I have install SuiteCRM version 7.7.8 when i create new opportunities and linked to accounts and contacts, the accounts visible opportunities but contacts not show (have subpanels).

I check relate between Account - Contacts is many-many, contact to oppotunities is many-many.

Please help me resolve this problem!

Could you please attach some screenshots of the Opportunity and its sub panels and one of the contacts subpanels. Could you also try going into Repair in the admin module and run a Quick Repair and Rebuild and Rebuild Relationships
