tennis retirement rules cooked my bet, thought it should be void not loss

Was on a pretty good run last night and decided to switch things up with some live tennis bets. Took a shot on a match, looked solid until one player retired halfway through the second set. Thought my bet would get voided since the full match wasn’t played, but nope, it just counted as a loss. Kinda wild to me, especially since different places seem to handle retirements in all sorts of ways.

Do you guys have a spot that actually voids bets in these cases, or is this just how it goes everywhere?
