deleted but not gone

Thanks for this great plugin..Wish i saw it this morning…I created 3 sliders via import samples..was screwing around so much i just deleted all 3 and they were gone in admin and database..created slider #4 and it is alone in the admin and db and showing up when SC is used, but slider 1 and 2 and 3 are still showing up when called even though they are gone from the admin and database–cleared cache did not help
