Sudden change of page numbering while re-ordening pages

[Bopper]

Hi,

I am blind user (just started) and follwowing occured during page reordening:
I had a page "not parent" I changed it to connect it as a sub page (parent to...). So far ok.....
While moving a page up with the arrows the number counting changed just like that (I think  ). I now have two main pages numbered with "2" and also two series of subpages 2.1 and so on. Now the menu is showing all those pages when clicking just one 
Cannot find how to restore the numbering while page sequence is veru ok now.

HELP!! 

Regards and thanks

On older versions this was a bug but it was supposed to have been fixed, for now you may want to try hitting the page reorder button then just hit submit, this used to fix wrong page ordering/numbers...
