Slider - Slider loop and Blank slide after the last one


I have a problem with slider.
Indeed, I setup my slider to make a loop and I want to see directly the first slide after the new one.
However, after the last slide I have to click two times one the arrow before the first slide appears.
I have “two blank slide” and I can’t remove them because I haven’t create them. I don’t setup slide with blank background but they’re here.
I think it’s a common topic with slider but I cannot find the solution.
Someone can help me with this topic ?

Thank you very much community !
