Plugin Lightbox Image load twice the images

Hello,
I’m building my homepage, and I’m using the Lightbox Image plugin inside a RepeatingGruop, along with a DataType images Database.
The search in the RepeatingGroup works fine, and the main page show all the images fitting the constraints based on the filename.
But when I click on a picture and the image slide is shown, it loads the images twice.
I’ve not any Workflow events in the page. All is done inside the plugin. I’ve verified also that all the settings are correct.
I don’t know what more can I do.

Please, can you help me?
Thanks

can you show some images of the options and settings???
