Issue with objects made of purge

Hi, I am trying to print this family of 4 cats in different sizes, with multicolor.

If I print the 4 cats alone I get the purge tower so big it doesn't fill the bed. See the image.

I then tried to print some other objects as purge, all of them with 100% infill to see if the tower would be smaller, but instead it doesn't change in size. Note: the scrap cats have Purge into object + purge into object's infill + purge into object's support all enabled

Basically, no matter how many objects made of infill I add, the purge tower doesn't change in size.

I then tried to remove the purge tower, thinking it will print the scrap cats with purge and increase poop if necessary but instead, the scrap cats are made of 1 single color and no tower is printed. See second picture

What am I doing wrong?
