MQD for 100 mile equals 10% of the tickets total fare value. 500 mile flight gets 50% and the 200 mile flights each get 20% as MQD. When you use a partially used ticket the system still sees the previously flown flights. Now that the mileage for each flight is different, the calculations change. If you go and look at the previous flown flights credit, they'll have been recalculated to be lower.
Ok, but there weren't any previously flown segments any of these tickets. The original tickets were purchased and then canceled prior to the flights due to the Covid-19 travel restrictions. The only thing that makes them different from any other time I have canceled a flight and used the credit was that these had the change fee waiver. I guess the other potential oddity is that both of the canceled tickets were quite a bit more expensive than the flights I bought with them - one was a $500 ticket (so has a couple hundred $ left as a voucher) and the other was over $700 & has about 400 left.
