Please help me!! Why is it when i airbrush a flat coat on my models, it always dries semi-gloss (or sometimes fully gloss)?

I've just sprayed an aircraft using Microscale Micro Flat with my Testors Aztek airbrush and its dried gloss!!! I've tried thinning it with water and acrylic thinners, both dry gloss.....

Any tips as to how i can achieve that matt finish? What is the best product to use? Come on people, get thinking, it's driving me bonkers!!!!

Hope someone can help,

Chris.
