DHIS2 version 2.31.9 maintenance page does not go to the second page

Hello. I have very unexpected issue in DHIS2 version 2.31.9.
We have a lot of data elements, more then 3000. After the upgrade to next version, all data correct, but maintenance page does not go further first page and shows only 50 of data elements. I’ve tried to rerun analytics, but nothing has changed.
Same issue I see on many maintenance options, category for example also does not go second page, and we have more then 50 categories.
