Compile as Kindle .mobi disabled

Any ideas on why on my iMac I am able to compile the scrivener doc of my manuscript BUT if I bring the same file to my MBPro the options are all greyed out (unavailable to select/edit) along with the actual compile button?

Please advise if anyone has a clue why this isn’t working on the MBPro.

Both are running latest OS (with all patches/updates) and latest Scrivener.

Is KindleGen installed? In quarantine? … -scrivener
