Sliders saving issue

The plugin was working fine until just now after I changed the Slide Info of one of my slide and saved it, the Name of my slider became “Untitled Slider” and the number of slides became “0”. When I click in to see the slides I saved, the slides are there. But on the dashboard it shows “0” slide, and so it doesn’t appear on my homepage of my website.

Anyway I can fix this?

Thanks!
