I'm not qualified to comment on the GIB labels (which is obviously incorrect in many cases) but if you think a bit more about it, bridge logic should lead you to the conclusion that your double of 4S should be for penalties.

Basically the rule is, if you've had a chance to make a takeout double of a suit but chose not to then later double that suit at a higher level, then double is penalties.

This is a good point but, you see, playing with GIB I give up bridge logic and do what the labels say because in by far the most cases GIB trusts its own labels whatever the bridge logic.

Playing online with GIB and than then posting on BBO when GIB does something you don't agree with is the wrong approach to improving your bridge.

You're much better to reach to other forum members (myself included) and play a game with them!
