Random characters in Pen Log

[nevat]

We are using Pen to load balancing a MariaDB Cluster (Galera). Looking at log file (var/log/pen.log), I can see random characters just before some SQL orders (marked in bold):

_SELECT DISTINCT ID FROM rundetails WHERE
.INSERT INTO rundetails (ID, JOB_ID, START_TIME, RUN_DURATION, RUN_OUTCOME,
.DELETE FROM rundetails WHERE ID IN (1604677)
dSELECT DISTINCT ID FROM rundetails WHERE
.INSERT INTO rundetails (ID, JOB_ID, START_TIME, RUN_DURATION, RUN_OUTCOME,
.DELETE FROM rundetails WHERE ID IN (1604678)
_SELECT DISTINCT ID FROM rundetails WHERE
.INSERT INTO rundetails (ID, JOB_ID, START_TIME, RUN_DURATION, RUN_OUTCOME,
.DELETE FROM rundetails WHERE ID IN (1604679)

I don't know if this is a Pen Log problem or Galera sending _SELECT, dSELECT, etc. instead of .SELECT.

There are any report/bug about it ?

Thanks.
