Multiple mysql image not working in Springboot and docker

I’m new on Springboot and docker.
I’m trying to create three different microservices and load them into docker.

Two of them start correctly while the last one returns the following error:

Caused by: com.mysql.cj.exceptions.CJException: Access denied for user 'db_user'@'%' to database 'PaymentDB' 

I can’t find the error. The configuration of the three microservices are exactly the same (sometimes I copied and paste the similar code and changed only the name for example from Catalog to Payment. Can You suggest me something?

This is the application.properties:

spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL8Dialect
spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:mysql://${PM_DATASOURCE_HOST}:${DATASOURCE_PORT}/${PM_DATASOURCE_NAME}?autoReconnect=true
spring.datasource.username=${DATASOURCE_USER}
spring.datasource.password=${DATASOURCE_PASSWORD}
spring.kafka.bootstrap-servers=kafka:9092
kafkaTopic=payment-topic

This is the .env :

DB_DATABASE_PAYMENT=PaymentDB
DB_HOST_PAYMENT=paymentmysqldb

DB_DATABASE_USER=UserDB
DB_HOST_USER=usermysqldb

DB_DATABASE_CATALOG=CatalogDB
DB_HOST_CATALOG=catalogmysqldb


DB_USER=db_user
DB_PASSWORD=alx2022
DB_ROOT_PASSWORD=user
DB_PORT=3306

This is the docker-compose.yml
