is the number of slides limited??

hi, i am just finding out that all is working fine with the first 2 images, then it doesn’t seem to save it properly (in the preview of slideshow options it shows 3 images correctly but not when loaded in template or in a post by shortcode.

a second test slider with different images won’t be found when tried in a post neither (‘No slide available, click here to add a new one’)?

WP version 4.2.5
