Malformed S1AP NAS-PDU

Hi All,

I'm getting "Malformed Packet: NAS-PDU" when trying to decode my S1AP Initial UE Message (Attach Request): https://drive.google.com/file/d/1Pg0kQd3ioBJMpqXpUw33olF5zLcr1uAo/view?usp=sharing

Item #1 NAS-PDU appears to include besides several others the last IE 40 05 70 40 26 00 00, which looks formatted as TLV with IEI=0x40, Length = 5 and Value = 70 40 26 00 00. What type of IE is that and why is it not decoding? I briefly checked 23.007 and 23.008 and didn't come across IEI 0x040 although pretty sure I'm overlooking it. My Wireshark version is 2.4.5 (v2.4.5-0-g153e867ef1).

Many thanks in advance!
