Following update to SPPBPro 3.8.5 (downloaded from Joomshaper), adding Addons fails with no error codes when attempting to add certain addons.

1. Create Article and use SPPB as the editor or an SPPPB Module
2. Add a Row
3. Add any of these Addons or edit existing addons as follows:

• {Alert}
• {Animated Header}
• {Article Scroller}
• {Button}
• {Countdown}
• {Feature Box}
• {Heading}
• {Image Content}
• {Image Layouts}
• {Image Overlay}
• {Navigation}
• {Person}
• {Pie Progress}
• {Price List}
• {Pricing Table}
• {Testimonials}
• {Testimonials Pro}
• {Text Block}

When adding or editing any of the above, all SPPB existing rows disappear from the page leaving only the:

ADD SECTION | IMPORT | EXPORT | PAGE TEMPLATES | UNDO row.

This is unacceptable!

What have you done and how does this get fixed URGENTLY?
