Hi Melanie,
For obvious security reasons I cannot give you the information you are requesting. However, if you use the “inspect element” feature in google chrome I would guess that you can identify the code error in your theme that is causing this. The theme code has not been altered from the package provided by your company.
My guess is that there is a coding issue between your theme and WooCommerce ratings. If you can point me in the right direction I can inspect code if necessary.
The following plugins are active on the website and may provide insight to the issue?
