"home" icon changed windows

[Android Question]

Samsung Galaxy Note 3
The five different windows, one have the 'house' icon, moved. Not sure if I did it somehow, but it's not on my home screen and I'd like to put it back.

thanks for your help

Can't you just press and hold then drag and drop it back where you want it?

tried that, it just lets you slide from window to window, putting up the corresponding window number but the 'house' stays.
