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.
When night comes creeping in,
Dark restless shades arise.
Prepare to crawl and run.
The Black is here tonight.
