listing multiple variation is nearly impossible!

[*harrypotter-store*]

I am having issues listing multiple variation listings. It stucks on saving changes a lot of time without any response. Whay is going on the site?

I am using google chrome version 

 58.0.3029.110 

Connection has been reset

It says on the bottom javascript;

eBay's bad programming and terrible leadership in regard to product variations needs to be addressed big time.
