Private Message Sent Box Not Storing Messages

My site works well in the community theme with the latest version of BP/WP, users can send and recieve messages, but when you go to the “sent” folder to see messages you’ve sent, there is nothing there. Also, what is “notices?” I’m knew to buddypress but not wordpress, so my apologies as I’m learning this. My url is I’ve modified the theme but nothing serious that I think would affect the private messages. Thanks, rg.
