When I send a book from calibre to my Kobo via USB, the book gets copied to the device and the metadata gets updated, but after ejecting, the meta data file gets reverted.
Next time I connect the device, calibre doesn't see the new book anymore. With Nickel, the same workflow does work correctly.

Scenario 1: Sending book from calibre to Kobo via USB when koreader is open

koreader is running
Connect USB to computer
"Share storage via USB?" -> Share
Send new book from Calibre to main memory
Check file on root of kobo: metadata.calibre: The new book gets an new entry there
Eject Kobo from Calibre
On Kobo, go to file explorer. New book is there as a file
Connect Kobo again via USB

Not OK: Check metadata.calibre: The entry for the new book is not there anymore.
Not OK: In Calibre the book is not shown as existing on device in library (Green mark)

Scenario 2: Sending book from calibre to Kobo via USB when nickel is open

Exit koreader
Nickel is running
Connect USB
Send new book from Calibre to main memory
Check file on root of kobo: metadata.calibre: The new book gets an new entry there
Eject Kobo from Calibre
Nickel shows import dialog
Open Koreder
Go to file explorer: New book is there as a file
Connect Kobo again via USB

OK: Check metadata.calibre: The entry for the new book is still there.
OK: In Calibre the book is shown as existing on device in library (Green check mark)

Why is scenario 2 with nickel working correctly but scenario 1 with koreader not? Is this a bug in koreader or am I missing something?

Device: Kobo Clara HD
Versions:
Original Firmware 4.26.16704
koreader v2021.05
