Additional information
The possible reason is that Long-term Statistics requires the entity to set the state_class and device_class attributes, while the File integration does not set them. To solve this issue, the file integration should set these attribuets or allow the user to set them in the config flow.
While this looks like a feature request, I still posted it here because it is an interoperability issue among first-party integrations.
