Problem zoho invoice in crm

Good morning i have an integration between zoho invoice and zoho crm but when i import quotes and invoice in a contact zoho crm i can see the link but when i'm going out from the page and i come back to the page i lose the link of zoho invoice.

I have another problem i can not import the invoice and quotes in zoho crm potential client is not possible to see the link also here in the potential?
