This is an intentional platform-wide behavior change from IFS Cloud 24R1 onward: overview tables now always display a field's value on one line in the grid itself (embedded line breaks are collapsed for display), with an ellipsis if the text doesn't fully fit. To see the full multiline content, hover over the field or use the field's editor button — both reveal the complete, properly formatted text without changing what's shown in the table cell itself.
