Need Boxing Prop Explanation

Please help:  Thank you.

Here are two prop bets live right now at BetED.  Can anyone explain to me the difference between these two options?

Fight Prop:
Pacquiao by Decision +280

What round will today's fight end?
Pacquiao by 12 Round Decision +1400


Why would the book offer basically the same exact bet at two very different prices?

It is very likely that the price is either incorrect, or Pac by KO in the 12th is +1400.

Even if you bet the +1400 and it is Pac by Decision, they won't honor the error.

Obvious line error, saw the same thing it will be no actioned

Yeah.  They changed it now.  Very likely locked in bets will be no action.  Def a mistake by the book.
