I am using logback for my application and find one more issue. I am not sure it's bug or I need to write my own class to overwrite the existing class.

I try to generate CSV file from my application and using fileHeader for the output.

1. It's working fine for first time, when log file is not existing. I have not try rollover yet, but I think it's fine as well. The head is on the first line of the file.
<encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder">
            <layout class="ch.qos.logback.classic.PatternLayout">
                <fileHeader>Time current max percentage</fileHeader>

2. question is when I restart my app, the log file exists there. The fileheader is append , this make the file has two head lines.
Because the property called "fileHeader", I thought only one header for one file.

So is this a bug? or I have to implement my own class to overwrite LayoutWrappingEncoder or PatternLayout classes.
