Painful, yes, but there is reasoning behind both sets. The Bowman Chrome - Prospects (#151-250) is a continuation of the Bowman - Chrome Prospects (#1-150) set. So not 2 distinct sets, but one set across two different releases.
As for Bowman Draft, they shortened the name to make it easier. Who kept want to use "Bowman Draft Picks and Prospects". Have you seen some of the crazy card numbers that led to BDPP-XXX to start.
My sins have come to face me, I can feel it
That I have lived my life in vain
And now I know I'll reap the seeds I've sown
