Looks like whatever program wrote that file set a bit that it shouldn't have in
the ending block length field.
I suggest you tell whoever's teaching the class that the file isn't valid, so
that they can get the file, and the program that wrote it, fixed.
(If they disagree that it's invalid, point them to
https://www.winpcap.org/ntar/draft/PCAP-DumpFileFormat.html#sectionblock
where it clearly gives the same description for *both* instances of the block
length field as a 32-bit length value and says of the second instance that
"This field is duplicated for permitting backward file navigation.".)
