Hi,
Why can't I make this part unique (see screenshot)?

You can't make something unique if it is the only one, it is already unique.

It is already 1 of 1, therefore unique

I have just notified that by myself and was to late to delete the thread (if possible).
Sorry

What misled me about this is that there is the option Make unique in the contextual menu, even though it is a single item, from which I concluded that there was some problem.
