I am working on a client site, and installed v1.3.7 of the FedEx module.. I can get rates when I use the shipping estimator, but in step 1 of the checkout, FedEx does not display at all as a shipping option.

So I rolled back to the v1.3.6 version of this module, and all works fine..

I'd love to get some feedback/ideas as to what might be the issue with v1.3.7, or can I just get way without running the latest version of the FedEx module since it's working as always??
