You need to be very careful regarding the sync of the Dolby E decode. Assuming you are using a DP572 to decode, the decode will probably be one 23.98 frame late. But that might not be the case because the encoding could have possibly compensated for that or it could even be two frames late if neither the encode or decode latency was compensated for. So, the LtRt might be one, two, or none frames out of sync with the Dolby E decoded audio.
