I'm sorry Cliff: the system sucks because there's a lot of edge case handling when they're dealing with millions of vendors selling literal hundreds of millions of SKUs.
Many of them autogenerated programmatically like "I love X" shirts, and X = some dictionary list; or bots built to crosslist Target/Walmart product over to Amazon etc. for arbitrage etc.
I hope someone from Amazon has reached out to you Cliff - my wife gifted my FIL one of your klein bottles and it's been an absolute delight going through the purchasing experience with you. Thank you for the joy you bring to us!
