There's your likely answer. You are young, which means you have a limited history and relatively thin profile. Your credit was probably borderline: not quite where it needs to be for an ED but good enough for a charge card. You'll get there in time.
A standard credit card is inherently riskier than a charge card. With a charge card you are required to pay in full every month. The first month that doesn't happen it will set off a red flag. A credit card gives you the freedom to carry a balance, which means it can take a lot longer for it to be apparent that you've gotten into financial trouble and/or won't be paying Amex back for all your charges
That's assuming that was your question. If there is anything else you wanted help on, we will be happy to do what we can.
