Recurring fee fails although auth.net authorized the transaction

I am fairly new to uc_recurring so I apologize if I am missing something obvious. My recurring fees have not been working. I could not see authorize.net's response until I applied the recent patch to not delete the failed order. Now when I look at the auth.net response it seems that the transaction was approved (see altered message below), yet I got a drupal error message stating: "Failed to capture recurring fee of 29.950 for product trial on order 1511." I may have something misconfigured, but in any case if auth.net says it is approved shouldn't drupal flag it as a success?

Debug response from authorize.net:
Array
(
[0] => "1"
[1] => "1"
[2] => "1"
[3] => "This transaction has been approved."
[4] => "kP5Hj6"
[5] => "Y"
[6] => "2151024870"
[7] => "1511"
[8] => "1x trial"
[9] => "9.95"
[10] => "CC"
[11] => "auth_capture"
[12] => "3"

[38] => "P"
[39] => "2"
