Photoshop Batch Aciton

I'm guessing that the other images don't have the layer name "nervy".

You should use relative keyboard shortcuts to select the layer rather than clicking on it when recording the action, or use a common generic name if clicking on the layer.

Showing screenshots of the layers panel for a few images would help to illustrate the layer structure and if it was consistent. For example always the top layer or the layer directly above the Background layer etc.

Relative Layer Keycuts:

Select/target front (top) layer = Option + .

Select/target next layer up = Option + ]
Select/target next layer down = Option + [
Select/target back (bottom) layer = Option + ,

Move current target layer to front (top) layer = Command + Shift + ]
Move current target layer up = Command + ]
Move current target layer down = Command + [
Move current target layer to back (bottom) layer = Command + Shift+ [

Windows users would swap the Command key for Ctrl and the Option key for Alt
