Problem with DVH results

Hi everybody, I have a problem with results from my dvh.lis file. When I run my simulation I score dose using USRBIN. When I want to create DVH plot with my voxel file, I get, that the dose for the PTV is same or less than for the OARs. When I show USRBIN in the geometry, I can clearly see, that the most dose should be in the PTV (enclosing picture)? You will find enclosed output from merging the dvh.lis file.
Thank you very much for your help, I am getting desperate.

Dear Vanda,

could you send upload .flair project file, so I can take a look?
