Please try a new workspace and import your project there, as a check. If it is still a problem, please raise this on our forums, if possible. You can post it here: https://www.genuitec.com/forums/topics/webclipse/webclipse-help/
If you could provide a screenshot, that would help us. Also, mention the release and package of eclipse that you are using (e.g. Oxygen, JEE package) and whether you have enabled the Darkest Dark theme and whether you have enabled DevStyle preview. Finally, please mention whether and how you have changed any of the appearance or editor settings.
