Page order sometimes not correct

[eva-andersen]

When viewing an individual page, and then clicking to the previous or next page sometimes results in rendering the wrong page order or skipping multiple pages (i.e. viewing page 5 --> clicking next page --> viewing page 17).

These problems always occurred in the BoE: keyword search --> selecting page to view (amp 1863 issue 02 page 393) --> clicking on the previous pages results in amp 1863 issue 01 page 394. (see: http://10.240.4.163/r/5FlxFkla7mI7)

Another clear example of wrong page orders. In the AMP installment of hg the pages jumped back and forth when clicking the "next page" button.
The sequence of pages was as follows:

1. amp 1889 issue 09 page 181 (http://10.240.4.163/r/Nif4DIYmhXGO)
2. amp 1889 issue 10 page 180 (http://10.240.4.163/r/r1XSXdDSXdq8)
3. amp 1889 issue 10 page 181 (http://10.240.4.163/r/e88ifnJdwDs2)
4. amp 1889 issue 09 page 182 (http://10.240.4.163/r/zrb-9WHjwTrk)
5. amp 1889 issue 10 page 182 (http://10.240.4.163/r/9hbIEMCQIyZh)
6. etc.

And another one (now using the "previous page" button):

1. amp 1890 issue 12 page 154 (http://10.240.4.163/r/uCj_X9eyq2Cb)
2. amp 1890 issue 11 page 165 (http://10.240.4.163/r/8GTB235y46aP)
3. amp 1890 issue 11 page 164 (http://10.240.4.163/r/gjOXg0RZF3Dd)
4. amp 1890 issue 12 page 153 (http://10.240.4.163/r/EnhCOwizeO37)
5. amp 1890 issue 11 page 163 (http://10.240.4.163/r/YHdAMwWO5qHF)
6. amp 1890 issue 12 page 152 (http://10.240.4.163/r/7jzI3dptbH1F)
7. etc.
