UPS bug in my cart

Hi everybody,

I am close to the end (or hope so!) in my opencart installation (1.4.9.3).
But after activating UPS shipping module, and entered all required info in the admin panel, going back to my store when I test purchasing an article the UPS option does appear as "United Parcel Service" without the selection buton on its right, has anyone this anomaly?

By the way very nice product this opencart.

Many thanks in advance...

Well, this morning the "error" has disappeared, so it seems to work again.
I will keep you updated if any issue again.

Best regards

Same thing is happening to me:
Right now it says:
Free Shipping
Free Shipping 0.00€
United Parcel Service (text_weight 0.60)

Thats it, nothing else
