hotel owner can't see bookings anymore in 2.6.9

[4riders]

Hi all
we installed a new version of 2.6.9 and now we are seeing a huge issues.
so when a user creates a booking the as an admin you can see the booking under admin/bookings.
BUT when you login as a hotel owner you CAN'T see the booking or edit or delete or change the status.
does anybody has an idea how to solve this?
this makes version 2.6.9 completely useless, since this is one of the core functionalities
thanks for your help
