Congrats, that is a nice starting CL. 
Hmmm
I got the letter from Capital One (via online) and states the reason WHY my application to QS was denied....interesting...
Thank you for applying for a credit card issued by Capital One. Unfortunately, after reviewing your
application, we cannot approve your request at this time. Please know that in the process of making
this decision, your credit score was not impacted.
The reason(s) for our decision are:
Based on your application information, there is a currently pending or recently processed
application with Capital One
I app'ed like almost 2 minutes AFTER my Platinum was approved for $3,000 so I guess either Capital One changed the rule for 2 apps=1 pull or I wasn't that fast enough LOL!

Honestly, I don't think it's either. Sometimes there's a glitch i

Go ahead a try to PC the Plat today. I have been following a thread the past couple of days about a guy that PC'd his less than 10days after approval and $0 use on it. He is trying to PC a new one he got last night today to see how early it can be done.
Give it a shot. Nothing to lose.
Skybuilder,
I recieved my Platinum card in the mail today activated it via online and setting up online account as well. I clicked to chat with rep. She said there's no offers to PC to QS, told me to try again in few days since it was opened 4/9. So I'll check again in few days 
Congrats!!! I also just got my first Cap One approval this week, the QS1, except my $300 SCL pales in comparison to yours. lol. Your scores are higher than mine, though, so I know I'll get there eventually.
Enjoy your new card and have a great weekend!

The same thing happened to me when I applied for QS1 and then apped for Platinum shortly after. I called Customer Service and that is the reason that they gave me. I think that until you get your card in the mail, it will show in their system as an active application. I am going to try applying for Platinum again once I have had my QS1 for a billing cycle or two, then I will be able to get rid of one of my starter cards - more specifically the one with the less than useful $175 CL that has decided to randomly stop reporting.
