My understanding is that "NASA Saturn V" set (21309) and its recent reissue (92176) are almost identical. Some of the printed parts appear in both inventories, but some are separate entries. Take for example White Slope 2 x 3 with Decoration (US flag):

So Brick Owl system saw a new ID and created a new entry, but you can request the merge of all these decorated parts.
BTW seems to be taken care off now, so Lawrence might have read this post.
