Icon Grid Flip Box.

This concerns Content item, then icon size.
(I think the title is not the same on the 4.7.1 French version)

1) After the upgrade from version 4.6.3.1 to 4.7.1, the look of the grid has changed. Now I have a line in the center of the video.
2) The most annoying thing is that I can’t find anymore the possibility to indicate the number of columns I want to have per line.

Here is the look I get after upgrading from version 4.6.3.1 to 4.7.1. Without modifying anything, the aspect is already not the same as the one I had with Version 4.6.3.1. but it is still acceptable :(

3) And if I change a parameter (For information I’ve increased the size of the “Title Font Sizes” font by 1 px. From 30 to 31px) I get something else as a rendering. I can no longer indicate the number of columns per line as with version 4.6.3.1.
I get anything with Version 4.7.1 ( click on the link to see)
