[Plugin: Scissors Continued] watermark logo appears twice

hello, all

i have tried several times to get this to work, installed then uninstalled – i only want to add a watermark, and for some reason the settings rae ignoring what i select, ie, i don’t want it on thumbnails but it shows up there anyway, and i see an older logo that i have removed underneath the newer one – seems like it’s hanging on to some stuff

should i do a manual deletion and start over? it will be great when i get it going

i also can’t add a watermark in the media library – nothing happens

thanks
