Missing File repair failed

Hi,
i have that Problem again. Last Time was the BackUp really fresh, so was the easier way, to build it new.
Now it’s older and a HDD with some BackUpFiles Crashed. Snapraid rebuild the most, but not all Files.
I tryed to make the rubuild over the Webinterface, like in the linked #howto: How to list / purge broken files
This is the Output:
