Disable expanding Text Appearance when copy&paste text with Appearance.

Hi there,

I have had an issue with the Appearance functions with text for quite a long time, tried to search for a solution but seems I am the only one who has this issue.

When I applied the extra new color(eg. white) to the text (area/point text are same),  and convert it to Rectangle in Appearance effect to have an automatic Variable white background effect which followed the text size length.
And when copy&paste this text, the new color Rectangle will become a individual path and the text has been duplicated.

Before Copy:

 Close-up to applied effect.
 This effect is done by only 1 object.

Pasted:

But every time I copy this area/point text and paste it, the new fill Rectangle will expand to a solid path.

  Appearance has been expanded to 3 objects:
 The 2 texts on the top and bottom are the same, repeated. The path is the white background.

But somehow holding option key drag is working, but it is annoying I can't copy and paste it to different files.

Here attached my Clipboard Handing setting. Maybe I have some setting related to this issue?

Version:

Adobe Illustrator 26.0.2
System:
MACOS Big Sur 11.2.3

Thanks all.
