URGENT naviance and common app, common app not accepting LORs

My school utilizes naviance for requesting and sending letters of rec, but I have to apply to some colleges using the common app. The common app will not give me the green check and let me submit my app even though I have synced it with naviance. In addition, when I try to invite teachers for the common app letters of rec it will not except one of my teachers saying that their email is already used on naviance but it will accept my other teacher. Please help I have a November 1st deadline.
