Details
If you insert a manual text in a new created row of a table you see yellow clamps around the text. This happens if you create a new row only. The new rows will be marked with an yellow line.
Solution
The 'Manual Text' : 'Highlight' toggle under Parts List : 'Workflow' settings is checked on. The setting indicates the cells have non automatic text in the cell text.
The 'Highlight' toggle can be checked off or the cell selected > MB3 > Automatic text in order to not see the manual text marking.
