Css Semantic UI responsive table won't collapse properly in Safari-open source projects Semantic-Org/Semantic-UI

I am currently using Semantic UI’s tables, which are supposed to be mobile-responsive (example and description here http://semantic-ui.com/collections/table.html)

My only problem is having apparently the same settings, Safari and Chrome will present mobile version of tables, on my website, in strangest ways, but definitely not blocks as in normally in their website.

I have added normalize.css but it seems to not work for this issue.

Am I missing something?

Thanks a lot in advance!
