Localization does not work in the packed project

Hello,
I have a problem with the localization. I have entered the translations in the Localization Dashboard and compiled them. Everything works fine in the editor. There I can change the language. But when the project is packed, the language files are missing and switching doesn’t work.

In the Project Setting under Package I have seen that in Show Localized nothing is displayed. Why are the languages not displayed? Even when I look at All, my translated languages are displayed with an exclamation mark. I have the feeling that my Unreal Engine does not know the translated languages.
After packing i can copy the “Localization” Folder from my Project in the Export Folder and the Translation works.
I am using the Unreal Engine 4.23.1 in my project. Does anyone have the same problem or can help me?
