UFW delete allow syntax for one particuar rule

[bpb_21]

I've got a silly little question about UFW. I set a rule like this:
"514/udp ALLOW 192.168.1.0/24"
I don't even remember exactly what I typed to set it. Anyway, on further reflection, I want to delete this rule. I've tried every combination of "to", "from", "port", "proto", etc. and received every combination of:
"ERROR: Bad destination address", "ERROR: Wrong number of arguments", "ERROR: Need 'from' or 'to' with 'port'", and read the man ufw pages until my eyes watered. I can't for the life of me figure out how to delete this rule. I'm rapidly approaching the point of absolute fury in trying to get rid of this rule. I even removed and reinstalled UFW. Still there. Rather than destroy a perfectly good computer, well - what was a perfectly good computer until this UFW thing, I figured I'd kindly ask the community for a tip. (If anyone tells me to use Google or read the man pages, a: I've already done that to the point of exhaustion, and b: it will probably push me over the edge into an absolute berzerk rage which we'll all regret!)
Thanks for any/all help!

I've always just deleted by rule number e.g.

$ sudo ufw status numbered
Status: active

     To                         Action      From
     --                         ------      ----
[ 1] 22/tcp                     ALLOW IN    192.168.1.0/24
[ 2] 80/tcp                     ALLOW IN    192.168.1.0/24

$ sudo ufw delete 2
Deleting:
 allow from 192.168.1.0/24 to any port 80 proto tcp

I've always just deleted by rule number e.g.

Oh, I've tried by number. Believe me.

     To                         Action      From
     --                         ------      ----
[ 1] 514/udp                    ALLOW IN    192.168.1.0/24

sudo ufw delete 1

The result of that command is the same as running sudo ufw --help
It's the strangest thing. Also infuriating. Did I mention that? I meant to. I even did su - to become the root user and then tried all of the above. Same effect.
