Multiple identical entries in context menu

When I right click on a directory in a list a couple of my context menu items appear multiple times. This does not happen in explorer or xplorer2. The screenshot shows grepWin is listed 3 times in different places and WizTree appears twice. I have tried hunting down any settings that might help but was unsuccesful. Any ideas? I already have a lot of items in my context menu, duplicates and triplicates are not a welcome addition.

Thanks for the report. We have fixed this for the next update.
