Is 38 minutes break on manual entry does not count ?
The 38 minute break added manually will count as a WTD break but not as a driving break because you hadn’t done any driving before having it.
You cannot have a driving break until you’ve done some driving.

that what was showing as 15 min break taken on display.
I doubt that, if the tachograph was showing a 15 minute break it would have recorded a 15 minute break.
I’m guessing you calculated the break from the time on the clock instead.
This thread shows where you should be taking the break times from viewtopic.php?f=5&t=146150&p=2309253#p2309253
