Jupyter notebook run on Visual Studio Code - Gathered code problem

I am a newbie to Jupyter notebook. I would like to know how the cancel the Gathered code icon after we run a specific cell. For example, when I run a cell, there are two icons appear, 1. change to markdown and 2. gathered code (represented as 3 boxes->1 box icon). From what I observe, it delete all the variables executed beforehand and the current execution making the next execution (the cell afterwards) in error.

How can I cancel this?
