autocalculate FTP not working

Autocalc is enabled but it does not ‘detect new ftp’.

Also my maximum 20min avg power is not registered as a ‘personal record’.

I have a max 20mins power of 277, but the ftp is still on 215. 

I have now manually entered my ftp, but would be interested in the figure calculated bij Garmin.

Anyone with a similar issue?
