hm ok just found that in some Version of FortiOS there is only one ID column in gui though.
But I'll explain it thoough:
This is what the Policy View in gui looks like on my 92D here in FOS 6.2.10. That's the latest FOS release available for a 92D. It only has the column ID which then is the policy ID. I guess you are missing this column.
So if you hoover your mouse over the "ID" Column header (or what is the most left column in your view) you will see a filter and a gear icon appear. Cllick the gear icon then:
This will pop up the column selection. Check if "ID" is activated (green "v" left to it indicates this). If not cllick it to activate it and then click "Apply". Then the column should be there again.
Though I remember there is some FGT and/or FOS Versions that do have two ID columns in gui. In this case there would be some column named "Policy ID" or similar in that menue too.
