HEC RAS 2D Boundary and 2D Flow Area not appearing in Unsteady flow viewer

[Peppers]

I added a 2D flow area and boundary in RAS Mapper, but they don't populate in Unsteady Flow - any reason why this could be?

I need them to appear in unsteady flow to then populate a precipitation rain on grid.

See attachment.

Usually saving your edits in RASmapper and closing RAS would help.
Or close Rasmpper and open the Geometric Editor. Open your Geometry A2_NE and check for the boundary conditions line.
