BUG in MT5 close by functionality.

What is the proper place to submit bug reports for MT5?

I found a bug in the "close by" user interface, which results in the wrong order being closed.

If you sort the order list, then your selection will no longer match the actual order that will be closed.

How to fix? 

Very annoying when you need to close a specific trade, but this UI grabs a random trade from the list instead.
