Possible bug in USPS extension in version 1.4.4

[Heemet]

Hello,

I recently upgraded to version 1.4.4.  Thanks to everyone who worked hard on this new version.

I installed the new USPS extension, and I have noticed there are two bugs:
1.) The only shipping options that appear are Priority Mail, Priority Mail Express, and USPS Ground Advantage.  See screenshot in attachment 1.

These are the only three options despite all shipping options being selected in my configuration, except for USPS Ground Advantage (more on that below).  See screenshot in attachment 2.

2). Note that USPS Ground Advantage is turned off in my instance of the extension.  If I turn it on, USPS Ground Advantage appears twice in the shipping estimate as a shipping option.  See screenshot in attachment 3.

I tried a fresh installation of v. 1.4.4, and I noticed the same bug.  My error log is clear.

Thanks!
