When using a parameter on a slicer, output the value desired, not a random value. Current State:
Version: 2.108.997.0 64-bit (August 2022)
Set up a parameter with whole number increments from 1 to 2,000,000. Drop that parameter into a slicer, and this is what happens. If I add the same parameter to the filter pane, it works as expected. If I use a range on the slicer and narrow it down to a single value it works, but if I try to type in a single value, it settles on a random value in relative proximilty to the value entered.
