Looks like you have the ME version installed which would default to right to left reading.
Yes, I tried resetting the preferences - it's still coming up with the same default for the pages.
It would be odd if I did have the ME version, it's work installed and I'm in the UK. Not impossible though - is there anyway of confirming it is the ME version?
And in the meantime any other suggestions of how to get the pages the right way round?!
What exact version number of InDesign are you using?
In any case you are using RTL (Right-To-Left) binding of a document by default (?).
Is it only this document? Or is RTL binding on every new document you are creating?
You have not necessarily a ME version installed, but you (or someone else) did perhaps a "scripting experiment" with the defaults.
However, re-installing InDesign or trashing the prefs should be a solution then.
Further exploration reveals it is indeed an ME version, so I think a reinstall is necessary!
What version of ID? If it’s Creative Cloud, use the CC Desktop app to uninstall it. Then make sure to choose UK English as the language for the new installation.
