"Unexpected number of faces" from Apple Photos

"Unexpected number of faces" from Apple Photos

Hello,

Have just for the first time tried to import my Apple Photos library using Avalanche for Lightroom. Seems to work well, apart from it gives the message "Unexpected number of face objects. Was expecting 602 but only 5 were converted". Indeed, when opening in Lightroom, it has only converted 5.

Could this be something to do with the fact that my Photos library was originally an iPhotos library (and indeed I still have the "hard-linked" original in place)?

Thanks

Jonny
