admin/settings/cloudzoom not showing preset

hi,

I am looking at this module because i'd like to test is for a new site i am building.
In the admin panel i made a preset 'demo' but the admin page show none.
After i made a new preset called 'demo' i got a error in my log : Duplicate entry,
So I think the preset does exist, but it only doen not show in the admin panel..

any ideas?
