There are problems with the template after updating from Joomla 3.6.5 to 3.7.0.
And at the Layout Conficuration, check out these two screenshots!
One sees exactly the difference, which does not work!
I think you should look the same for the Joomla Update!
I'm back on Joomla 3.6.5 at least until it is fixed.
Thank you in advance.
