Internal hard drive recognized as External which handicaps OneDrive

I reinstalled macOS from scratch using a newly released cloverefi bootloader the other day and set the user folder to a hard drive hooked on via motherboard SATA while the system remains on the ssd. OneDrive was initialized and synced correctly.

Today, however, it says the location can’t be used anymore as it resides on an external hard drive. My settings with an ssd + a hard drive worked well on 10.13.1 before I carried out the overhaul. So I guess there must be some changes in cloverefi that resulted in this issue. Can I fix this by clover configuration, esp. by changing settings of ACPI or adopting/forsaking specific kexts?
