Are the templates meant for Gimp or for Photoshop? AFAIK in Gimp changing the layer name doesn't change the contents. To change the text you use the Text tool () and click on the text layer to edit it. This assumes that the layer is a "text layer" and not a plain raster layer. These layers are displayed with a T icon in the layers list:
If the layer is a plain raster layer you have to recreate it from scratch. Sometimes you can recover the data from its previous life as a text layer (font, text...).
