[TYPO3-dam] Edit the Labels in the backend ... How?

[Oliver Rasche]

Hello everyone,

I have been having troubles editing the labels of the formfields in the 
backend of the DAM extension. To be specific, I am talking about the 
fields (referring to the media item) you see when you click on the edit 
button of the media item. There, for example, I would like to edit the 
label of the field "Copyright" to i.e. "Owner" - I located the 
corresponding file (locallang_db.xml) and edited the corresponding entry 
(I have done this by using the extension a4n_edit_locallang).

My changes are successfully saved, but in the backend the label still 
reads "Copyright".

Where am I missing something?

Greetings :)
