Parent Product review not showing on child variants?

[yodelay]

Hi all,

I'm setting up the review and rating system for my client. It's all good, except I just noticed that the test review I made isn't displaying on the child variants.

You can see what I mean here: http://www.pinkcola.co.uk/shop/low-rise/colombian-bleach-rip-detail

The default parent item shows the review and rating - select a variant and the review&rating will disappear.

Any ideas?

J: 2.5.17

Let me know if you need any more information!

Many thanks!
