IDM 4.8.7 - Forms - dynamic Entity - localizedName

Hello,

IDM version 4.8.7 (Forms version ->The version that came with IDM 4.8.7 as an optional one)
I have a Dynamic Entity as a component. There I have stored a localizedString as display value. However, it only ever takes the English translation and ignores the browser language or the language that is stored for the user. Do I have a misconfiguration here, or is my expectation simply wrong?

Best regards,

Tobias

EDIT:

It seems like the forms will use the language definied here:

Not sure if I like this, but I will have a deeper look into it to utilize this function in a  - for me - useful way
