Hi,

It is because Dissect T-PDU option must be enabled in the GTP protocol
preference. If you disable this option, you will get the former addresses.

You can do following:

Edit menu -> preferences -> protocols -> GTP -> disable dissect T-PDU

Hope this resolves your problem.

Thanks Regards,
Satish
