BE2012 is ejecting Tapes when ejecting is disabled

Hi,

i have an issue with BE2012.

I have a small customer with 5 VMs to backup. The job runs B2D and then directly duplicate to tape.

Since one week the server starts to eject the tape (standalone tape drive) after every duplicate job. The option for ejecting tapes after completion is not selected.

Any idea what could cause this behaviour?

Regards
