Pressing emax bridges

[DALTD]

I'm having some problems pressing anterior bridges in emax.
They are distorting? ,the external shape is good , but internally the walls of preps either increase in size mesial or distally or thin out mesial or distally.
Can anyone offer practical advise.
I use pressvest speed, EP3000, regularly calibrated,

Spruing technique?
