Comments/Review sections text doesn't set div size in WooCommerce Theme

I'm playing around with a WP theme and WooCommerce. I have a basic product added, however the reviews/comments on the products don't seem to display any text. If you take a look at the screenshot below you'll see that there is a box/div created for the comment, however the text inside of this is not visible.

Does anyone have any ideas what could be causing this?
