Multiline allow_duplicates=>true config eleminating duplicates

Hello,

    I am using logstash 2.3.1. I have created a config where I have used a multiline filter as one event in my log spans accross multiple lines.
    Apart from other filters which I have in my config, my last filter is : 
     multiline {
		pattern => "Phase\s\d"
		negate => true
		what => previous
		periodic_flush => true
		allow_duplicates => true
           }

      In this filter I want to club all lines into one field at the same time I do not want to remove any duplicates. The field in question contains record counts out of each component in a program, which can be similar. However when I get the output it is dedupped. Can anyone help on this? 
     I saw a few discussions where it was raised as a bug in version 1.4.2 and later some fix was put in place. Can anyone tell me if that fix worked and is that fix incorporated in the version I am using (version -2.3.1) .

Thanks

Can you format your post please, it's very hard to read with such wide lines.

Hello Mark,

             I have tried to get the lines shorter. Please see if this helps:

Can anyone help me out with this? Looks like multiline is not functioning as expected. Does anyone have a solution to this?
