Here the correction has been deleted.

Time laps cannot be manually edited or individually deleted - they are controlled only by the Start/Stop button of the "Do" view.

It is possible, however, to reset all the time of the current activity to 0 from the "Reset" view, accessible from the "More" view.

The reason for not allowing editing time laps is to preserve the integrity of the historical records, which time laps are. This is especially important in a business setting when timing is performed by employees and the records are kept for the benefit of a company.
