Transaction models with other connection failed

Hi guys, I have a project with 2 connections (mysql, and postgresql), postgresql is default connection in DI as $di->set("db", func....) and Mysql is $di->set("db-cms", func...), When I try to do a transaction with phalcon transaction manager in mysql models its not working I get an error because it takes the postgresql connection ""i guess"" because not recognize table from transaction.

Look error:
