Hi Mike,
Thank you.

We are doing well. I hope you and your family are safe.

Please replace your display name filter

function my_bp_displayed_user_fullname() {
	global $bp;

	return $bp->displayed_user->userdata->user_login;
}
add_filter( 'bp_displayed_user_fullname' , 'my_bp_displayed_user_fullname' );

with this

function my_bp_displayed_user_fullname( $name ) {
	return bp_get_displayed_user_username();
}

add_filter( 'bp_displayed_user_fullname', 'my_bp_displayed_user_fullname' );

That will fix it.

You are welcome.
I am glad it worked.
