Neither of those two citations actually list or enumerate people losing any value of their deposits. They just describe the process by which it would happen.
(That's a lot of banks! The US system seems quite fragmented?)
If you select "All Banks" in the drop down at the bottom and run a report, you see a bunch of "Final" dividends where the percent paid is less than 100%. I'm pretty sure that's people losing value of their deposits.
(remember, those are 'dividends to claimants' and the claimant listed is almost always 'depositors')
Basically there are banks that will divide your money amongst a bunch of independent banks, and let you access the money as if it were all in one bank.

If you go here, you see depositors not being made whole:

But $250,000 of insurance for each account is much better than none.
