Why does creating a language copy of language-masters/en also create a copy in the global folder in AEMaaCS?

Hi,

I'm working on a site structure in AEM (AEMaaCS) using this layout:

/content/my-site
├── language-masters
│   └─ en
└── global
│   └─ en

When I use the Create Language Copy wizard from /content/my-site/language-masters/en and choose a new language (e.g., fr), AEM automatically creates:

1. /content/my-site/language-masters/fr – which I expected

2. But also: /content/my-site/global/fr – which I didn’t explicitly request

   1. The content inside the global contains only 3 pages from the original language master

Why does this happen and is there any way to prevent it?
