It's already set to minecraft java edition, this bug happened after i ran the game through multimc5, could that be the problem?

When I start the timer after a couple of seconds the in-game time shows 9:45:25.

I've google and looked in the Livesplit settings but I can't find anything and don't know much about Livesplit.

If anyone have had this bug happen to them and/or knows how to fix it, plz help
