Cannot delete plate or measurement from Columbus

We are having trouble deleting plates and measurements from our Columbus server. Specifically, we have a plate that was read ~50 times for a stress test, so in our Columbus structure, we see a single plate with ~50 measurements. We are unable to delete either a single measurement or the parent plate folder. Other plates from the same user can be deleted without any issues. Are there any other options for deleting this data, perhaps at the command line?

Thanks in advance for your help.
