301 redirect problem

Hi! I'm having issues with creating working 301 redirects. I've done this before with another Squarespace site, so I'm not sure why this time it's not working. I've contacted support and followed their suggestions to fix the issue, but still no luck.

I don't want to create redirects for the whole shop section until I've got this sorted!

Here are the examples of my redirects that don't seem to be working:www.meadowgatenursery.co.uk/shop/anemanthele-lessoniana-stipa-arundinacea-2mj3z-b3ta2 -> /shop/anemanthele-lessoniana 301www.meadowgatenursery.co.uk/shop/andropogon-scoparius-prairie-blues -> /shop/andropogon-prairie-blues 301www.meadowgatenursery.co.uk/shop/achnatherum-calamagrostis-stipa-calamagrostis -> /shop/stipa-calamagrostis 301

The old url's aren't automatically taking you through to the shortened url page and I'm just getting 'this page is missing' type errors.

Thanks in advance!
