Is it possible for iCloud to add duplicate authorizations for iTunes and Music?

Hi,

In all I have 3 powerbooks, 2 running Sierra (with iTunes) and one Sonoma (with Music). The Sonoma one and one of both Sierra are synching perfectly well with the iCloud, from whatever app (iTunes or Music) I downloaded the music from. The 3. one however (Sierra) makes me problems : In Account I cannot authorise this computer as "You cannot authorise more than 5 computers". In my cloud there are however listed but 3 computers, besides of my iPhone and my watch, both of which don't count as far as I understood. Could it be that the cloud adds per powerbook 2 authorisations (one for iTunes and one for Music) so that finally I totalise 6 authorisations instead of 3? Sounds rather crazy, I agree, but in the mean I don't have any other explanation.

Any help is wellcome...

Greetings,

Marc
