The version of Lightning Pro in my environment is older.
So, the problem may doesn’t occur in an environment that’s using the latest version of Lightning Pro.
Thank you for information about the problem.

>>I checked Lightning Pro latest version but not appear problem.
Umm…
If that’s right, the cause of problem maybe in the latest version(v4.4.4 ; as of Sep. 29 2021,JST) of “Duplicate Page” plugin it self, not in Lightning Pro.
