SiteOrigin page builder – featured Image

Hi everybody, I'm actually facing a problem by using Site Origin Page Builder to create my own pages. The trouble ist that, until the last update of SiteOrigin (V. 2.6.3), the featured images I selected don't appear anymore on the Slider on my Homepage. When I load an Archive of my Page with an older version of SiteOrigin, no more problem. I tried till hours to fix the problem, but no way to find a solution. Is there anybody who is facing the same problem who can help me ? Thanks in Advance for your help Flo
