only one column showing up

Hi all
Trying to trouble shoot a problem that has occurred after updating latest woocommerce build and woocommerce product archive customiser build.

The shop pages of categories are only displaying one column now despite the fact that it is defined in woocommerce>settings>product as 3 columns
A product category here

Originally the categories was displaying in a grid format.

If I go one level up into the shop it is displaying as 3 columns. Shop page here

I’m not sure if there is conflict or something causing this.

Would really appreciate some assistance in resolving this issue.

Thanks in advance.
