My workspace in Indesign CC 2015 seems to have changed all of a sudden, and my swatch palette no longer displays icons beside the names of the colours, so I can't tell what's a spot colour, what's cmyk etc.
Have tried going through all the workspaces (advanced, digital publishing etc.) and resetting them but seems to make no difference.
Any idea what has happened?
Have you started to see it after upgrading to InDesign 11.4 ?
If that is not the case, please upgrade to latest InDesign version.
