I am using the Export to Excel plug-in - which is working fine, but I can't

I am using the Export to Excel plug-in - which is working fine, but I can't get the resulting Excel report to display my formatting correctly (specifically 'currency'). I have columns that contain dollar amounts and formatted them as 'currency' (also tried 'accounting' format) in the template, but when the report is generated - those columns are all formatted as 'general' even though the columns in the template are clearly formatted as 'accounting' for these columns. Any idea why this is happening...and how to resolve this? If it helps - I've attached my template.
