docker-compose volumes not persisting after executing "docker-compose down"

I have a docker project which uses docker-compose to stand up an API container and a database container. I also have it setup to create volumes for uploads and logs. When I build a new image, and then stand it up using docker-compose up, any data that was previously in the logs or uploads ceases to exist, but the data in our db-data volume persists. What do I need to change in my process and/or config to preserve the data in those other two volumes?

Here’s how we stand up the docker:

docker-compose down
docker build -t api:latest .
docker save -o api.tar api:latest postgres:14
docker load -i api.tar
docker-compose up -d

Here’s the Dockerfile:

# syntax=docker/dockerfile:1
