Can you give the exact MaxScale version you are using? 2.21 is not a valid MaxScale version.
MaxScale does not set tx_isolation by itself but if you are referring to a problem in your application, you can use the regexfilter module to modify the SQL to use transaction_isolation instead of tx_isolation.
