Common App/ Naviance Help

My school began using Naviance this year, so any college-related document is now requested and uploaded through there. One of my recommendations is from a teacher who no longer attends my school, so their name is not on Naviance for me to request a recommendation. When I go on Common App, it mentions that my school uses Naviance for recommendation requests and to go to my counselor to see what to do. My counselor just told me to put the recommendation as “other recommender”. Is that fine? Wouldn’t that make it seem like I only have one teacher recommendation instead of two?
