I have problem with PDF export too under version 167! I have a project, and with version 162 export is correct, but under 167 not. Ok, here is steps: - create a project with start on left side. - make 8 pages. I have first two pages the cover, third is inside cover, and fourth is start of content. - add frames, textboxes, background pictures with layers. - I deleted first three pages, and set document to start on right   Here's bugs: - background layer goes to top. Why? - after sorting export to PDF, but show hidden layers, or missing layers in PDF, but project see there, and good.   I installed 162 version to back, and export saved project and export to PDF: correct. Install version 167, open same project, select PDF export (same export profile), and exported PDF is wrong, missing parts, layers no there, many page incorrect.
