'Next' and 'previous' project links not showing up

Site URL: https://circle-broccoli-e8wk.squarespace.com/

Hi lovely community,

I'm having trouble with a client site - it seems just like a glitch but perhaps there's a logical reason why I'm having this issue.

I've created 3 x projects, and am able to reshuffle the order of them, but it seems that whichever one is last doesn't get linked to. So, Project One only links forward, and Project Two only links back.

Ideally, I'd like all three projects to link both forwards and back.

Any ideas?

Many thanks,

Laura
