Color styles missing on cloning the blocks

[ajosys]

We are working on an existing Craft website for our clients. We have upgraded Craft 2.7 website to Craft 3.6. We have a valid license of LJ Color Picker plugin

We are using NEO plugin for blocks on pages. Now the issue is that when we clone any section on any page then color styles, button styles (used by LJ color picker) do not copy to the new cloned section. The styles get changed or missed.

Attached are couple of examples of what is happening.

Now our website is Live and we have found this issue, which is critical.
Can you please let us know what is solution for that. Your help would be highly appreciated.

Steps to reproduce

1. Create new NEO block on any page, and put some color styles on Buttons, links etc.
2. Use LJ Color picker fields on these Button Styles, Link colors, Line colors
3. Clone the same block,
4. Here you will see in new cloned block that Color styles are changed or completely missed.
