Yes that is the correct website.
Alright so here we go.
I made updates in the CSS settings I wanted to preserve, so I was using my old CSS files after updating Helix, which also included the old bootstrap file (V4)...so that was what you were seeing on your end. So what I did was simply replace the bootstrap.min.css file in the template/css/ folder to the latest V5 (and not update Helix), and now the animations are working.
So basically, using the old template.css file after the update was causing the issue for some reason.
Do you think what I did should suffice? (do you see any outlying issues)
