Coercion dots on sub VIs using a strict type defined cluster

[MoWW]

Hello,

I seem to be having trouble learning how to use strict type defined controls, so would someone please help?

Will you tell me why the coercion dot is on the sub VI's and how may I prevent its apperance?
Will you tell me how I can link 'CtlsToWLp' (a cluster) in Main.vi and 'Clust Refnum' in WLp1.vi and WLp2.vi to the same .ctl?

The LV 7.0 .llb is attached.

Thanks,
             Morris W.
