UserData goes empty when I use restore link

Hello all,
I've created a toolbox and saved all the data in UserData. I've made the toolbox a library and after I copy the library into a normal model I disable the link.
The UserData data is still present, but when I restore the link to the library the UserData = [];
Why is this happening ? I need to restore the link in the models when I make small updates to the library.
Best Regards, Adrian

You are talking about Simulink, correctly? UserData are usually volatile, such that a reloading of the object must initialize it before using.

Setting UserDataPersitent does:
The following command saves the user data associated with a block in the model file of the model containing the block.
Does this mean, that you have to save the block to store the user data also? If so, did you save the block after setting the UserData?

I do not understand the 2nd sentence. Splitting this sentence into smaller parts might support my understanding as a non-native speaker.
However, I'm convinced that the bahaviour of the UserData is explained exactly and exhaustively in the documentation of Simulink.
