I’ve been testing this out and it seems to be working for me. There does seem to be an issue with it not taking affect right away. When I tried it the updates were not shown and then when I removed it that took a while. There was a transient set that I needed to delete. This is the only thing that I can come up with as a possibility. If this isn’t it then maybe there is something else, maybe another filter that’s changing it.
