This is a strange one: we use this font https://fonts.adobe.com/fonts/lus (you have to put a 't' on the end of that url, Uservoice thinks it's rude, apparently) it's Regular and Display weights. On two computers this shows up as (syntax here is [Font Family] / [Font Style]) Lus(t) / Regular and Lus(t) Display / Regular, respectively. On three others they show up as Lus(t) / Regular and Lus(t) / Display and there seems to be no way to align them.

I've attached a screenshot of how the taskbar shows font on the machines that separate them out.

The first two computers are a Windows 10 desktop and a Mac OS Big Sur Intel laptop; the other three are two Mac OS Catalina iMacs and a Mac OS Big Sur Intel laptop. All running InDesign 2022.

On layouts where the fonts are separated out into different families; the ones which don't separate them out have the fonts in square braces; throw up the Find/Replace fonts dialogue (and fail to find them), and highlight offending instances in pink. But, crucially, they actually display the font correctly on the layout - and will happily export to PDF correctly, without substituting a default font.

Any ideas?

Thanks
