Thanks for getting back to me.
I’ve tried that filter and it partially works. On the place category backend screen I can see the new icons appearing. However, they are not being re-coloured (all are still B&w, but I’ve used the same SVG files for re-colouring elsewhere so they are definitely fillable) and on the map they are appearing as the default icon (have cleared my local cache and the website cache but no changes).
