Make sure it's transparent like the rest of the strip.

You just need to extend the strip another 32 pixels to the right in order to make space. Each icon is located on a strip and has its own square of 32x32 pixels, and the game just counts squares until it gets to the right icon. You may need to download a plugin so that the programme can work with that file type. It's in gfx/interface/icon_religious.dds. It sounds like the only thing you're missing is localisation, unless there's a mismatch between spellings in religion.txt and your pop files. I'm not sure you're allowed to use the same icon twice, actually.
