Envira Plugin: When I click on a thumbnail I get another same photo over

I installed Envira plugin and created a Photo Album, created a page and put the shortcode inside it. Everything is normal except when I click on a thumbnail I get the picture enlarged and the lightbox bebneath it. To get the lightbox of the album to work normally I must first close the first that appears on top of the lightbox and then I get the photo lightbox work normally. I would be so grateful for any help to get rid of this abnormal case.
