"Request Publication" shown instead of "Publish Page" in Touch UI.

Hi everyone!

When I open any of existing pages on author environment and click on "Page information" button (at the top left corner):

     - at first I see "Request Publication" in dropdown menu;

     - then, I close menu and open it again (after 30sec-1minute):

     - after it I see "Publish Page".

Do you have any ideas what the possible solution for such issue? Also, on the pages where we have lots of components, I am waiting for publication ~ 3-4 minutes.

AEM version: 6.2 (without service packs)

Thanks in advance!
