Magic Submitter 'manage items' doesn't work, i can't send any bookmark. Help!

hello

i want to send a list of sites i added on magic submitter to bookmarking sites list only.
clicked on manage items and then bookmarking services and set up everything properly.

but i can't make the whole group of sites belong to a category at one click, i don't have any template.

after i run the schedule with 1min breaks, it marked as submitted and nothing happens, it only said "unable to submit" next to tumblr.

please help....

all i wanna do is use the bookmarking service there.

Thanks.
