I can't say anything off hand. if re-running fc-cache works, that
would mean all the installed files around fontconfig works as
expected.
There might be something breaking it such as linking older fontconfig
including static link, or loading own config.
Anyway, please check if any caches are updated after you run fc-cache
and confirm.
