1 Year Visit Visa Expiry Date extended more than a year on ABSHER!!!

Hi all,

I am confused as hell, my wife`s visit visa ought to expire in Feb 2019, but after applying for extension on absher yesterday, the visit visa expiry date is showing up as April 2019.

I had got 1 year VV for my wife, the exit re-entry details are as follows:

1. --- She entered KSA on 14-Feb-18 with a 90 day stay mentioned on visa.
2. --- First Extension applied on 5-May-18/ extended upto 13-Aug-18.
3. --- 13 to 20 June out of KSA.
4. --- 16 to 25 Aug out of KSA.
5. --- 5 Sep to 8 Oct out of KSA.
6. --- Date of entry 8-Oct-18, stay permissible till 6-Jan-18

I extended yesterday and i was expecting it will show VV expiry in Feb as it will complete a year in February, but instead the expiry date is 6-April-18.

Now my question is that if it was a 1 year VV started feb-18, how is it possible that i got the expiry date in April 2019? Is it some kind of error or this is possible normally? Is it possible to get it verified from anywhere?

NOTE: My wife went out of KSA 3 times during last year and yesterday was the SECOND EXTENSION only. PLEASE HELP WITH YOUR VALUABLE COMMENTS.
