ADEXL simulation results get mixed up

I've noticed something strange with ADEXL simulation.

I running the simulation through LSF, where I set my max. job numbers to be 16.

 Then I run a simulation with 9 sweeping points. First I saw that the 9 simulations (sweeping points) are all pending and then start to run. All 9 simulations are "running"

Then I change one parameter in the schematic, and run the same simulation again, while the first run is still running. Again I have 9 sweeping points. Now I see that the first 8 points of the second run are running, and the 9th point is pending. However, the strange thing is that the 9th point of my first run now also shows "pending", while it was running before. 

When I wait for all the simulation (sweeping points) to finish, then I see that the 9th point of my first run has the result from the second run, while the first 8 points all have the results from the first run. In other words, the simulation results from two separate ADEXL runs get mixed up, which is of course causing trouble for me.

I just don't know why this happens. I am wondering whether it is something due to the ADEXL, or something due to my LSF submission( the command used, etc.) 

I am posting the questions here to see if anyone has any comments on it.

Thanks!
