Plrease try to reapply Numbering&Section options, from de Pages menu, select the Automatic Page Numbering radio button.
If the file is somewhat corrupted, you can save it as *.IDML and then open it in InDesign to see it restored correctly.
looks like if the document was made in arabic type direction.
Try to use the information here: https://helpx.adobe.com/indesign/using/arabic-hebrew.html
or you mean the vertical lines near the digits? So, could you please show the Numbering & Section Options panel?
Yes, it could be it. I though about that possibility but I am not familiar with RTL, right to left, documents.
A capture of only the area of the pages panel will show bigger and easier to read. sequenece number is 3-2, 5-4,... and those lines are [ and ] (square brackets) ?
Yes the file is Arabic (RTL) but we used to have Arabic files before with no issues at all. kindly find the Numbering below
Any Help please?
Can you be very specific about what you are trying to solve?
Are you trying to get the pages to number from left to right?
