If you are Printing sections (Add section to layout or scaled section output), and tick the option to Add Plan of Collars to Layout the section no longer fits on the page.
Solution
This has always been a limitation of the design, as it does not require you to create and define the collar plan size first.
You will need to manually resize the section map frame to fit alongside the collar frame in the layout.
To check the scale is still correct, double left click to focus (blue highlight on frame edge) the section map, then right click and select Change View. This allows you to specify a cartographic scale.
It is also recommended to use MAP>Add to Map>Scalebar or LAYOUT>Scalebar as these are dynamic and will always display the correct scale.
