no options for unarmored defense proficiency

This is actually for 6.09.03 using Pathfinder 2 (from https://github.com/PCGen/pcgen-newsources/tree/master/pathfinder_2/core_rulebook)

I cannot seem to find any way to apply Unarmored Defense Proficiency - most posts online seem to assume it is already present but it doesn't appear to be. The value is 0 on the character sheet (which suggests that it is something that could/should be there).

If there is a workaround somewhere where I could add it manually it would be great, if not then this is simply for tracking purposes for you to look into when you have time.

Thanks for this project and app.
