Deleting of rejected Pictures not possible

In my Lightroom catalog I marked every ticket that I will delete later with "Rejected". Later I select delete all "Rejected" Pictures. Next step Lightroom ask me, only from the catalog or physical from the harddrive. My pictures are all stored on my server at home. Lightroom inform me that there is now carbage active on that hard drive. Than I found only the buttons abort, save as ... In the privios version I could delete the files without any problem. Now it is not possible. Is that problem known?

Is a solution available?

Thanks
