Fix Group Styles section

[RobertGlobant20]

Purpose

Fix in Group Styles section for showing styles added correctly
In a previous fix a vertical scrollbar was added generating that the GroupStyles items added are shown in only one column (previously two columns) so in this fix I'm reducing the width so two group styles are shown again in two columns.
