Hi @jpol,
Which platform did you use to generate your design ? Custom Design ? I'm not familiar with "Easy DoE", I think the "Custom Design" runs in the background in most cases but not sure.
Using the platform "Screening Design" (available in DoE, Classical, Two-level Screening, Screening Design) and specifying the factors and ranges as you did, I'm able to have a design respecting the inclusion of your "forced run" by selecting the option "Construct a main effect screening design" with minimum number of runs (4) :

Proposed design (1st run does correspond to your current process conditions, DoE attached):

If you want to be sure the platform will always generate this design (as the other "half" can also be proposed), you can click on the other option "Choose from a list of fractional factorial design" and select the first one with run size of 4 :

After clicking on "Continue", go into the panel "Display and Modify Design" and in the "Change Generating Rules", uncheck "+/-" and apply.
This will force the design creation to have a row with only minimum values (a row with "---"), corresponding to your current process settings (you can check the coded levels design in the related panel) :
