Caption Styles parameters not work

there is no captoin in the source code ...
please delete the module and recreate it (module manager >> new >> slideshow ck) to test with the default data

Sorry, I'm apologize my question was wrong. :oops:
I'd like have round corner not on caption but on the image slide like the screenshot here attached

in the file camera.css of the slideshow theme, try to add this

Thanks ced
