My One-Step Update CreditCard transactions look so different vs when I import them via QFX?

Question

I'm just getting back to Quicken after 10 years away. Since one-step update for Chase Credit Cards only goes back a few months, I took the time to convert all of my 2022 PDF statements to QFX files, and imported them. The imported statements worked great: They list Amazon as the Payee, and then put the specifics in the Memo field (like order number.  Or Home Depot as the Payee, and list the store number and location (city/state) in the memo field.  But when I use one-step update, all I get is Amazon or Home Depot in the payee field and the memo field is blank.  Is this normal? Or is there a way to tell Quicken how to parse this better using OneStep Update?

It could be because the exports are created by two different pieces of software.  The .QFX file downloads were generated from PDF statements and the OSU updates were generated by the aggregation service (Intuit) used by Quicken to collect the information and make it available for download.It would be like asking two authors to write books about baseball and expecting them to be the same while one wrote about Babe Ruth and the other about Roger Maris.

The real problem, as far as I can determine, is that Chase does not download any Memo Text, for any of their credit cards. 
However, for Amazon transactions they download a combination of vendor name and an encrypted invoice number, e.g., Amzn Mktp US*TX1234567  which, IMHO, is rather useless. How are we supposed to decrypt that number to match it to a true Invoice number?
For Amazon transactions I wish they would download the true Amazon Invoice Number in the Memo field. It's available because they print it on the paper statements.
