Sync Filter expiration

In my IB account, I manually increased a stock position and C2 put “Sync Filter” automatically. This is good as I don’t want C2 to auto sync the position until I manually remove them.

Now come my questions. When are the filters going to expire? What’s going to happen when the leader of the strategy closes the stock position? Does the filter prevents the closing? What I really need is that I still want the position even if the leader closes the position. Is that possible?

You should be able to see the filters (if active) in the autotrading page and eventually remove them If You wish so.
