In ReadyAPI 2.6.0, JDBCconnectionString are not updated when env changes using setActiveEnvironment

We recently upgraded the ReadyAPI project from v2.3.0 to c2.6.0. After upgrage we noticed that the connectionString in JDBC requests are getting hardcoded and not getting updated when the environment is changed via setActiveEnvironment from Java code.

In v2.3.0, connections string where saved as 

<con:connectionString>${#Project#ConnectionString}</con:connectionString>

whereas in v2.6.0 its set as 

<con:connectionString>jdbc:db2://<host>:<port>/<user>:user=${dev.DBUser};password=${dev.DBPassword};</con:connectionString>
