This is a question related to filter in version maxscale 2.2.21.

Hello, the DB is mysql version 8, and in our application, we set a filter to change the transaction check with tx_isolation to transaction_isolation by applying regex_filter. At this time, It seems that regex_filter intermittently changes tx_isolation to transaction_isolationtransaction_21. Is there a bug in maxscale 2.2.21? I also attached how the filter was configured. [filter_name] type=filter module=regexfilter match=tx_isolation replace=transaction_isolation

Please help me
