Emby with Rclone

Hello.
I have a question about Emby and Dropbox.
I mounted the Dropbox and created an encrypted drive. Moving it over to the Dropbox works too. But I can't mount the libraries in Emby. When I go to libraries, e.g. Movies, and then try to mount a folder, I only get as far as /home/user/mounts/rclone . Then it stops, but normally the Movies folder should appear there.

Does anyone know why this is?

Thanks in advance

I can't see the red border at all.
