Correct. As mentioned above I have the store card which is why I'm confused of them not letting me allocate payments. Unless that's the reason why, because it's store card and not an actual credit card? But still weird that they allow my at paypal credit, but not Amazon.
Either way my main concern is trying to understand why the Allocate option doesn't work correctly. So i can make payments towards non promo purchases. 
You need to look up in your T&Cs how payments will be allocated, they are not the same through all of Synchs cards.

And you had already selected option 3 before the $165 purchase?
This is an issue that I have run into numerous times with the Amazon Store Card. It's a PITA and their reps, typically understanding of the issue, don't seem to know how to actually fix it any longer. I had mine set up the same as you and as recently as last month, had the same problem. Finally got someone on the phone who understood the issue and supposedly fixed it, but it still didn't work completely and I was left with a much lower promo balance than what I should have had. It's not in your head; it's a real thing. What's strange is other Synchrony cards don't even have the allocation option on the dashboard, yet I've had reps for other cards of theirs reference the ability to do this with their cards. I've had months where I made a payment for exactly the amount that I spent in excess of the promo and it got applied correctly. I've had others where it didn't. It's a big reason Synchrony will never be a primary spending card in my lineup.
