Wrong currency symbol at check out

Hi,

I had reported this earlier that my clients on checkout see the correct currency amount but the symbol that appears for them is the symbol selected while they were browsing the store.

I have the plug in configured on checkout to only 1 currency (OMR), all other currencies disabled, also enabled cart page and I switched off pay in many currencies. For now I have switched off the plug-in to avoid client frustration, but I would really like to get it working correctly.
