Shipping started only showing one option in checkout VM1.1.9

[roggy1]

I have an issue with the shipping module for VM 1.1.9.  We had set up different rate options for different countries e.g standard US & Canada, express US & Canada.  In the checkout at the shipping method stage this appeared as a list and the customer could select the method.  I haven't changed anything to the site (I really haven't) but this has stopped working.  Now only one method will show at a time. 

I am not a developer and before I speak to one I wanted to see of anyone had a similar problem or knew if it was a simple fix. 

Many thanks
