Problem with morph particles at final render

hello. i am trying to make an animation with fluid particles like this video tutorial on youtube. https://youtu.be/64VXx6aKg28 the problem is my render on viewport is different than the final render. the liquid is not the same. i made it like how i want to be on the viewport render. when i try to make the final render the liquid is very few and unstable. the difference is big. i dont know why. and the morph cant not be completed to the other object because of not so many liquid it is not enough like on viewport. at viewport render is ok. i added like the video a remesh modifier, smooth modifier, and displace modifier on my liquid. am i doing something wrong there with the settings? i baked all the physics too. anyone help?
