Branch log messages contains related branch's log messages

What steps will reproduce the problem?
1. Add a branch repo to monitor e.g. svn+ssh://domain/svn/branch/branch_1
2. Add a branch repo to monitor e.g. svn+ssh://domain/svn/branch/branch_3
(branch_3 was created using TortoiseSVN from branch_1 in the SVN repository)
3.

What is the expected output? What do you see instead?
Expected to see log messages for branch_3 only, instead I see log messages
from branch_1 also.

What version of the product are you using? On what operating system?
1.5.1.382, Windows Xp

Please provide any additional information below.
If I understand correctly related branches are grouped together in
CommitMonitor under the repository's trunk URL. Under such a grouping I
have 3 different branches. One of these branches (branch_2) was monitored
by an older version of CommitMonitor and only shows that particular
branch's log messages. With CommitMonitor version 1.5.1.382, the newly
added branch_3 (of the 3 branches) shows log messages from branch_1 also.
Is this supposed to happen? Is there any way to filter log message specific
to this branch_3 alone?
