This is what the debugger outputs for parsing one of the tests for mil-std-2045, test2045msghdr1.
It detects that this is bitOrder leastSignificantBitFirst data and so presents the data Right-to-Left order, which is good.
However, this is gibberish, as the bytes of this data (left-to-right) are E4 67 00 80 55....
So presented Right-to-left the values in the bytes shouldn't change. But if you look at the data dump above, the bytes are 4e 76 00 08 55.... which means the nibbles of each byte have been swapped.
That's just plain wrong. Bit order doesn't change the numeric value of any byte.
These displays are useless.
