Hi Popov,

I have notice in the past few days an issue when running multiple windows of the  EA Studio Reactor mode with Generator, Optimizer, All Data Validation, Monte Carlo Validation, and Multi Market Validation turned on.  The problem I saw was the number in the Collection Page does not sync up with the strategies generated at the bottom of the Reactor page. I did this in two different computers and in 5min and 15min and both shows the same problems. 
I did also try to run Reactor mode individually with Generator, Optimizer, All Data Valid, Monte Carlo Valid, and MMV separately and adding them one by one to see if they have the same problem. I looks like the Collection sync issue does not show up with Generator, Optimizer, All Data Valid, Monte Carlo Valid turned on individually or together.  The Collection sync issue shows up most of the time when the Multi Market Validation is turned on along with the other validation mode. 
I don't remember seeing the collection page issue pops up since I have been using EA studio for the past few months.  The filter records in the Collection is set default (all zero).  Changing the filter records or clicking on the REFRESH button in the Collection does not fix the issue. 
Attached are samples of the collection number not matching to the output of the Reactor page.
