Fedora caches information about the underlying filesystem and changes won't be reflected when requests can be served from the cache. In cases where changes to the underlying filesystem are expected and need to be reflected with some regularity, simple configuration changes may be of service.
The main property that affects the lifetime of cached representation of the file system is "cacheTtlSeconds" which is a hint (not a hard mandate) about how long the cache should remain active. A low time, like a few seconds may be best suited to a filesystem that's likely to change. A higher time (minutes or hours) may allow better performance over a more static file system.
The basic configuration is explained here.
