Check renovation filter settings.
Check if all stories are selected and if all grid elements are selected in the section settings under 'grid tool'.
Change status from Auto-rebuild to drawing, confirm setting (ok). Go back in to settings and change it back to Auto-rebuild.
If all these things do not help, sulk in a corner sipping coffee.
