shipping tables disappear since update to woocommerce 2.5.2

Hi,

I updated to the latest version and now I can’t input any shipping tables. I add them, hit save, and they disappear. Any ideas?

Just so you know, I am not the original developer of the site, so don’t have access to the template.

This is very time sensitive, as shipping cannot be added to orders and since it’s a flower shop and valentines, a fix is needed asap.
