Issue when cloning or copying Matrix Field

[yawuar]

Describe the bug

I've got a field called Content Blocks, structured as a Matrix and managed with MatrixMate for better organization. It's a Matrix containing numerous nested Supertable and Matrix fields. However, attempts to clone or copy specific blocks within it aren't yielding results. To troubleshoot, I duplicated the Content Blocks field using the Field Manager plugin, and surprisingly, the cloning and copying functions seem to be working flawlessly in the duplicate, as demonstrated in the attached video.

1. Create a matrix block containing numerous nested SuperTable/Matrix fields and save it.
2. Attempt to duplicate or clone the matrix block using the "Smith" functionality.

At first, I thought it might be a MatrixMate conflict, but from the looks of it, you're using that for the duplicated field too? I would also say send me an export of your field, but if that's working for you, I'm not sure if it'll not work for me.

When cloning, what does the Network request look like?
