Describe the bug If I click on the Sampler | Select a Sampler option the selection box opens but only the message "Loading Samplers ..." is being displayed, and no samplers are listed for selection. Changing model doesn't make any difference.

To Reproduce Steps to reproduce the behavior: as above described, search for the list of samplers but none is displayed

Expected behavior The list of available samplers/schedulers should be retrieved and displayed in the selection box for selection.
