Modifying a datapack. The duration of the effect not go over 30 second despite I setting it to 50

I set the duration of the effects to 50sec to make the regeneneration effect regenerate 20hp, but after testing it out in game. The duration is 30 second despite I setting it to 50. How do I make it go up to 50?
