duplicate key value violates unique constraint "io_storages_localfilesexportstoragelink_annotation_id_key" DETAIL: Key (annotation_id)=(25) already exists.

Describe the bug when submitting an annotation show error:

duplicate key value violates unique constraint "io_storages_localfilesexportstoragelink_annotation_id_key"
DETAIL:  Key (annotation_id)=(25) already exists.

To Reproduce Steps to reproduce the behavior: I am new to label studio, I using these step to install label studio:

create a yml file like this:

#   Optional: Specify SSL termination certificate & key
#   Just drop your cert.pem and cert.key into folder 'deploy/nginx/certs'
#      - NGINX_SSL_CERT=/certs/cert.pem
#      - NGINX_SSL_CERT_KEY=/certs/cert.key
volumes:
  - ./mydata:/label-studio/data:rw
  - ./deploy/nginx/certs:/certs:ro
  - /shared/public/data:/data:rw
#   Optional: Override nginx default conf
#      - ./deploy/my.conf:/etc/nginx/nginx.conf
command: nginx

restart: unless-stopped
# Optional: Enable TLS on PostgreSQL
# Just drop your server.crt and server.key into folder 'deploy/pgsql/certs'
# NOTE: Both files must have permissions u=rw (0600) or less
#    command: >
#      -c ssl=on

2- call `docker-compose up -d`
3- then add source/target local storage  
4- start annotating images
5- when click submit show error
