A temporary work around might be, under the character's 'Attributes & Abilities' tab, to manually add these two attributes if they don't already exist, then set the values accordingly; spell_attack_bonus spell_save_dc Spell attack bonus would equal the monk's Wisdom mod + proficiency bonus. Spell save DC equals 8+Wisdom mod+proficiency bonus. The downside is that whenever your proficiency bonus or wisdom mod increased/decreased, you'd have to remember to manually change those attributes.
