The above shared page (screenshot) is created using shortcodes which is the old way of creating pages.
Instead of shortcodes you can use siteorigin widgets .
You can remove that codes and use the widget “Device Slider”.
Directly converting the pages which is created by shortcodes to siteorigin builder pages won’t work properly. You need to recreate each section using the siteorigin widgets.
You were right. The imported widgets are showing siteorigin widget instead of the actual widget, device slider. I tried importing pagebuilder demo layout in a fresh page and this issue exists.
Will get back to you on this shortly.
Sorry for the trouble caused.
