Dynamics for different voices of the piano does not work

Hello there! As you can see in the screenshot, I set the dynamics for each voice. There are 3 voices: 1st-the theme in the treble key, 2nd-the melody in the bass key, 3rd-the actual bass. For the 1st set mf with a pressing force of 70, for the 2nd set f with a pressing force of 95, for the 3rd set put mp with a pressing force of 50. For each one in the inspector (I pressed F8 to open it), I put "Batch" in the column "dynamics coverage". As a result, in the next bar, EVERYTHING is played with the force of pressing 95, that is, with forte.
So the question is: What do I need to do to make different voices sound with different pressure? When I write a piece for the choir, there is generally a cacophony due to this dynamic!
and since I'm Russian, I apologize for my English
