Custom Tech Tree in TOA not working

Hi. I have been messing with the tech eidtor quite a bit of late. however I cannot get any of my custom techs to show in game when choosing from a custom race. Tried creating Spectral_techtree for example but it would not show up in the list of choices. I have also tried altering existing ones, also without result. The techs on existing ones remained the same evewn though changed in the editor.  What am I doing wrong or is this a bug?? Thanks for any help!!
