I do not use that software and have no ideas about that.
That sounds like an Apple problem. (I assume that it shows correctly in the calibre book viewer.)

Maybe calibre has requirement to be picky because some target reading system is picky. But I wonder if it would be worth filling issue about it. I have mostly just been generating ePub from Amazon purchases and then only spot checking the results. With AZW3 I would usually fix it in that source and only then worry about ePub issues, but it will all be KFX going forward.
Thorium Reader is based on Readium open source project. I use it mostly for checking FXL books as calibre viewer does not support these. For me it could be complete replacement for calibre viewer as I don't need AZW3 reader for anything (and calibre converts those to ePub anyway) and it looks better than calibre viewer and is zippy.
In this case it isn't fixed layout. I haven't had it urp on anything before trying this one. I don't see related issue on their
GitHub repo so I will file one when I have a chance. Seems like if it passes epubcheck, Thorium should handle it.
Thorium Reader has (free) EPUB/PDF/audiobook apps for Windows, macOS and Linux, and it's updated regularly.

Readium Project Goals
The fundamental goal of the Readium project is to produce a set of robust, performant, spec-compliant reading system toolkits that support digital publishing formats and can be deployed in browsers or built into mobile or desktop reading applications.

This contains list of resources and apps based on it.

I'll see what Sigil is able to do to fix things as @JSWolf suggested.
