Combine Results From 2 Queries

I'm trying to create a list of orders in my db that has been created correctly (some orders are not dealt with correctly...) An order should go from "open -> assigned" to "assigned -> responded" status.

I got the following query:

select org.name, count(order) AS correct, NULL AS Total
from order
left join orderstatus o1 on order.id = o1.order_id
left join orderstatus o2 on order.id = o2.order_id
left join org on order.orgid on user.id
where
o1.status = 'Open -> Assigned'
and o2.status = 'Assigned -> Responded'
and o1.time_stamp < o2.time_stamp


This gives me a list of all organisations with the correct number of orders in the system...

But now I need to add the total number of tickets they got in the system. So I was thinking about a union with a query without the were constraints

UNION 'with the above query
select org.name, NULL AS correct, count(order) AS Total
from order
left join orderstatus o1 on order.id = o1.order_id
left join orderstatus o2 on order.id = o2.order_id
left join org on order.orgid on user.id

..but that gives me a list like this:

name correct total
org1 324 NULL
org1 NULL 423

How can I combine them, or maybe doing it a better way?
