WordPress – Problem with visual composer row & remove titles from page

I have a problem with my website.

Steps to reproduce:
1. Add a row using the 'visual composer' plugin and select edit row settings.
2. Change the row stretch to 'stretch row' (see screenshot 1 attachment)
3. The 'I can no longer remove this row or edit this row. The button to edit row settings disappears and the row is stuck on my page.
See screenshot2 attachment for the problem row that won't delete (highlighted red).
