I'm not sure what more you would need from me,* but I've noticed that filling in Custom Spells (in particular Custom Spell 6) will cause an error with the Character Summary spell listing where every line will be replaced with #N/A. Removing the text from the Name field of Custom Spell 6 will replace the error text with the information in the Short Description line. Removing text from the Name field for Custom Spell 5 will replace the error text with the Short Description of Custom Spell 5. edit: It seems to be doing with all of the Custom Spells, actually. I removed the text from the Name field of the other sections and saw it happening with each of them, pushing the Short Description to fill all of the lines in the Character Summary's Spell List.
I assumed it was user error from previous uses of the generator compounding, but I downloaded a fresh copy of the file and only changed the Custom Spells section and still had it happen.
*I can provide screenshots and the file with the errors if you find you can't replicate the error on your own. e: Version 2.27
