I have taken this as far as I can with Support.  I have an Email in to Craig Faris (I believe the Project Lead for Fabrication ESTmep) stating that we need a SP for ESTmep 2019 out quickly...

If there is anything anyone else knows that I can do to help this fix get into the next service pack, please let me know...

We are NOT able to use ESTmep 2019 until this and the Color By Legend showing up by default, is fixed...
