Hi guys,
Help needed with content blocks please. When I edit a page I'm unable to remove a single width content block by clicking the remove ' x ' button. This is what happens:


I have a workaround for this, but it's not ideal:
1. Delete the block by pressing the 'x' button
2. Click 'Save'
3. Click 'Preview' to see the change
4. Back in the edit window press 'F5' on the keyboard to refresh the window.
Any ideas would be greatly appreciated.
Richard
