Power data and ftp auto update

My power data bests have not updated for a very long time. I wonder if other users have spotted this. I compare the data in the zwift table to my data extracted from zwiftpower and they are miles out.

Further to this i havent had an auto update of ftp for over a year as far as i can remember. This despite improving by 20% in same period.

Zwift insist that these features are working but the reality is different. Anyone else seen these issues?
