ID 2015 page tab sheet display
Dear forum,
I'm having to work in InDesign CC 2015 (11.1.0.122 x64 build) and in the page tab display there are a number of pages that are missing on the right hand side. On the attached the pages are 12, 13, 14, 15 and 28, 19, 30, 31 are all missing disappearing off the edge.
This happens in all builds of CC 2015 and I'm not able to upgrade to 2018 as not everyone in my organisation has 2018 installed yet.
Any help or guidance would be very helpful please.
Thanks
