Epub page order wrong in ADE

Hi,

Since updating to ADE 4.5, epubs I generate from InDesign CC 2015, don't read in the correct page order in ADE. So, viewing two pages on screen – pages 6 and 7, for example – I see 7 on the left and 6 on the right, and so on.

The epubs read correctly in every other reader I try - both software readers on my PC and actual devices (Kindle, ipad, Android) - and they're also fine in Calibre and Sigil viewers.

I only use ADE for preliminary checks (it's set as the default reader), so it's not massively important, but I'm just curious as to whether anybody else has experienced this?

I use Windows 10.
