No - TVDB is community contributed and erroneously - and against their own rules - had it as S9. There is literally nothing connecting Showtime to TVDB - so not sure what you’re talking about.
TVDB’s information they “have” is user contributed - its not linked to anything, so how is it showtime’s fault for TVDB breaking their own rules and treating a new, unique series as a season?
I don’t believe showtime ever classified as as a new season nor can I find any reference as such.
