Multiple Identical Results in Genetic Optimization

 
When using genetic optimization in the latest build of MT4 I need to filter the results in Excel afterwards because the exact same result for a particular set of parameters will appear multiple times (possible 100X) in my set of results for an optimization pass.

Is this a bug, or is it something to do with the coding of my EA's? It seems to occur with every EA I test using 'genetic optimization'.

Is there a code snippet that can be added to an EA to prevent this?

Please help..
 
Download latest build MetaTreader 4 from "Downloads" (July 10 2007). This bug is fixed.
