I am unable to design units with armor or buy armor from the shop with my sovergn. (Game version 1.11 on Vista)

I have researched the propper technology (equipment --> Armor --> Light Armor --> Heavy Armor) and have lots of materials, gold and metal. When I go to desing a unit all other items show up, but when I click the armor tab only shields show up... I have done this with multiple games now (started from scratch) and even researched up the magical armor tree...

What am I doing wrong?
