hex decode > md3a    (user password=|lp:7|+_v$A v98)

What am I doing wrong?

It does look weird. But I'm not sure if the (user password) part is intended. I haven't  cracked pdf's for ages.
But some hashing algos - and pdf could be one of them I think - have a lot of false positives. You should run hashcat with
--keep-guessing

"I tried running it, but I ended up with a lot of hex values. After decoding, I got outputs like:

• md3a
  (user password =
  |lp:7|+_v$A v98
  )
  
• 061028
  (user password =
  gg2DN#nT%Nx5;Mp
  )
  
• lollie02
  (user password =
  C7%9X>t!W{?;5
  )
  

Not sure if these are false positives or if I'm missing something here."
