I can’t tell from the screen but I’m thinking a few things…
1. the alpha of the object is not the same as the psd layer. <– maybe you selected the wrong alpha when applying the material to the object in Proj. Man?
2. the missed object is not under the same material in the projection man panel.
if all else fails, create a new material/projection camera relationship and apply it only to the needed geometry, then use the same image or even a modified psd with only the needed texture/alpha.
or…
group all objects with the same texture together, then apply the projection to the group collectively.
good luck,
