BUG trainer FTP changes not taken over in trainer

When I change the FTP for a workout (because JOIN does not support indoor/outdoor FTP differences) it does not take over these changes in the trainer module. example :
I open the training @265W FTP, in the workout screen I change the FTP to 325. The workout breakdown changes the values to the new FTP setting (first is 60-70% or 195-228W). When I start the training the first target is 172W - which is 65% of 265W. The trainer does not change to the newly set FTP setting.
