Some font thing failed

Ubuntu 20.04, flatpak current master, testing, develop

I imported a bunch of PDFs, most show only images,
no text, the console which started Paperwork reports
‘some font thing failed’ when these are selected.

The boxes are there when ‘Highlight words’ is turned on,
the text appears when a box is mouse hovered, search
works.

Suggestions?

Thanks,
Kent
