I wish I could edit the page to see the preview. I copied the page's code and previewed on another wiki (broken templates) but the columns were fine so the styling wasn't the issue (though you could clean it up by using site css, center tags are depreciated). A template may be an issue though without being able to preview the page, I can't offer much more help (I don't have a test wiki nor do I wanna create one with all those templates).

My first impression is that this is a wiki issue, not a Fandom bug.
