Rooextend Bundle not installable

I bought RooExtend extensions as a bundle. In License Manager there is no separate possibility to type in the license key. Got only one key for the total bundle. Doing this in the separate extensions does not work either. When typing in a separately bought license for RooPlay for example, everything is ok.

Any hints, what I might be doing wrong?

The problem is solved. I have to answer it on my own:

The bundle is only for the rooExtend-Box. As I am using a Rasperry Pi 4 as a DIY-project, I have to choose the extensions as single licensed versions.

But no problem, the payment will be refunded.
