CMS item reference not working properly?

Hey guys,

I need your help with the following. Not sure if anyone has encountered the same issue. I was trying to create a go next button from one collection item to another. I used reference field in collection setting and assigned each item the next one. eg. item1 has a reference of item1, item2 has item3, etc. When I bind them and linked them on the collection template the links are all messed up and everytime i publish without modifying anything the same link goes to a different page. Here’s the screenshot of my setting and result:

Hopefully someone has a solution or alternatives out here.

Thanks in advance,
