Seems odd that eBay would change address in checkout from given...

...shipping address on purchase page. I am talking about purposely leaving out apt number (apt. 19e).

Yes, not only possible, it is a fact. Buyer included apartment number in purchase - ebay left it out after payment.

Seen with my own eyes.

Sorry to contradict you but leaving out an apartment originally included is a change.

Where do you see an address other than what is given with their payment?  Are you saying it was on the item sold email but missing on the print label screen?
