Spring Boot 2.2.6 Java Application executes sql query on wrong database - spring-boot

Question

I will try to explain the problem as clean as possible. First let me give your some details.
We have two seperate repositories set up for two different databases: one Postgres, one MsSQL.
We assume to have given correct a transactionmanager annotation for this very query, which you can see in the code shared below.
One of the problems is that we recieve a 'ERROR: relation "dbo.sometable" does not exist' error which indicates an execution on the wrong database (postgres) and we confirmed this by checking pg_log.
And here is the bigger problem. The error above does not occur on every build. Each build either executes the query on the "correct" or "wrong" database and this behaviour consists for each container image despite how many time we kill or torture it, it never changes.
