Problem with updating prices

Hi People,

I have come across a problem when trying to update the prices of my products.

Admin section - setup / product/services / Edit Product / Pricing

whmcspricing.jpg

Cannot enable or disable or enter Quarterly etc
Prices already enabled can be edited and saved but cannot add new preice for Quarterly/Semi-Annually/ Biennially/Triennially even after enabling.

Can any one help with this?

Thanks in advance :)
