2 Service Desk Projects with separate email addresses but duplicate tickets.

[Cyril Philemon]

I have a client that created a 2nd Service Desk Project in Cloud, both have different email addresses associated to it and the request type for both emailed requests are different. 

I have only 1 Incoming Mail Handler and 1 Mail server. 

If I send a request to Project A then the ticket appears in the queue for Project A. 
If I send a request to Project B then a ticket appears in the queue for both Project A and B.

Can't figure out what I'm missing that is causing this. 
Any suggestions would be great.

Hello,

Have a look at the query of this queue in Project A? Does it take tickets from both projects? 
What the JQL query for this queue in Project A?

[Cyril Philemon]

JQL is the same for both:
resolution = Unresolved ORDER BY "Time to resolution" ASC

Since they are separate projects they only show the tickets associated to each.
