Not understanding BIAB mash instructions

I think I have my equipment profile setup correctly for a no sparge BIAB with the medium body BIAB mash profile chosen.  However in the mash timer instructions it seems to be having me add water at three steps...  Mash in, Mash out and a fly sparge at Mash complete.  This is on my Android phone so it could be an issue with the mobile software version.

Or I'm just not understanding what it's saying...

Check the mash profile and make sure that it is set for BIAB, full volume mash.  If this is checked off, then there should be no instructions for fly sparging.

Use this to set up your mash profile. There are some key tips included like; turn OFF the "Adjust Temp for Equip" option and to be sure you enter the actual grain temp. Those two things will give you the most strike temp possible.
