Zotero cannot navigate the Table of Content (outline) of an epub file - but it works on Calibre

Per the title: when I open the ebook (.epub) on Calibre, everything works normally. I can navigate to different chapters using the Table of Content (outline). But the exact same file on Zotero? While I can open it and read it just fine, for some reason I cannot navigate by clicking chapter titles on the ToC.

Weirdly, other ebook files don't seem to have this problem, the ToCs are navigable in Zotero.

Anyone know what the problem is? And how to fix it? All help is much appreciated.

The ebook in question is "Sweet Anticipation" by David Huron, sized 1.64MB, if it matters.

OS: Windows 11
Version: Zotero 7.0.16 (64-bit)
