Strange legend generated in chart

[adam.muller]

Hello everyone,

I have recently updated a report in Cognos (8.4) and realized that it started generating a weird line of text into chart's legends.

On the left side of the screenshot you can see how the chart looks in report studio. On the right side is the screenshot of actual report.

My question is - where does the "Negative response rate, Activation response rate, ..." come from and how can I get rid of it?

Any help appreciated,
