I am creating a level 5 Half-Orc Druid. At which level The character is to have 3 Cantrips, 4 Level 1 Spell Slots, 3 Level 2 Slots, and 2 Level 3 Slots. by selecting my chosen cantrips I am unable to select the 2 Prepared Spell Slots for my Level 3 Spells. This is standard in the Player handbook and general rules. Of which, I have purchased the; Players Handbook, Dungeon Masters Guide, and Xanathar's Guide to Everything, from the Marketplace. Can anyone please help me identify why this is occurring. Thank you all for your kind guidance and assistance. 

Spell slots ≠ spells prepared
