I have created D&D 5e Ranger, Sorcerer and Warlock characters in PCGen 6.06.01 and 6.08.00 RC2
using the D&D 5e System Reference Document 5.1 data set
and found the same bug affecting each character generation.
The "Spells Known" does not allow lower level spells to be added or swaped
despite there being higher level spell slots available.
The error generated is "You can only learn 0 spells for level 1 and there are no higher level spots available."
Switching “Use Higher Spell slots” appears to fix it, butis that something that can be set as a default for 5e?
The would need a assistance to implement. has limited control over GUI control options in the program.
