Paid the difference in fare class, and change fee waived from K to R by nice agent....so the receipt all showed the 1.5 multiplier on the breakdown of the MP Accrual... but unfortunately I only printed after the bump, so they all showed as PZ vs B, and R for the two outbound segments (LAX_SFO, SFO-TPE)

After a few back and forths w MP, the were able to find I originally paid for R.

Agree/confirm if it's an INVOL/OPUP or upgrades, you get what you originally pay for.

Takeaway, pdf your reciepts at each step of the way (rookie mistake on my part that caused a few more hoops to jump through)
