Sorry, I have no idea why it works on certain page with your site origin page builder plugin and doesn’t work on others. Maybe it has memory issue if too many of that widget is used in the same page. Memory issue can cause certain settings to get lost in the process of saving, because the server drops the operation.
Sorry, I do not have the knowledge to troubleshoot site origin page builder plugin.
Our widgets are only tested with our theme and for sidebar only.
