Connection Database Name

Last week i’ve got a issue with the database name in the gateway. In the gateway, we have already some database connections, so when i want to create a new one i wrote a name and i didn’t got any error. i tested it and the connection work fine. But i started to have some connection error in an other project in the same gateway. then i realize the new connection then i made was the same name to an other connection but i was in lowercase.
did anyone as ever notice this probleme?
