Two PEDs on VISA

[bksram]

Hi,

We are in US for 6 years.

Got H1/H4 extension from 04-mar-2012 to 03-mar-2015.

Wife went for Stamping at chennai (She already had a visa valid til 03-mar-2012)

Old visa cancelled.

Visa got approved and got new VISA to see an annotation "Not Valid until 20 Feb 2012"

Sent it back for correction.

Got visa back today. The cancelled the old one and gave a new one.

But in the annotation column now she is having two entries which reads like this

PED: 03 MAR 2012

PED: 03 MAR 2015

Any body having any idea about this?

Thanks
