Hi there! I am brand new to python and I am already lost. This is probably such a basic question, but I am having an issue when I run my code. When I try to run my code in markdown, the cells run twice. I added a screenshot of my page to show what is happening. When I run one line of code, its starts at [1], but when I run more lines it goes straight to [3], [5], [7]. I do not know if this means the code is running twice but I can’t figure out what is causing this.

See [Cell numbering broken on new Jupyter lab/notebook](https://discourse.jupyter.org/t/cell-numbering-broken-on-new-jupyter-lab-notebook/26585) .

Especially [here](https://discourse.jupyter.org/t/cell-numbering-broken-on-new-jupyter-lab-notebook/26585/5) how to disable the extension that causes the issue. Or update the extension to 4.0.21 or later.

Or, [here](https://discourse.jupyter.org/t/cell-numbering-broken-on-new-jupyter-lab-notebook/26585/5) said updating Anaconda and Jupyter fixed. As you are starting out, that may be the easiest.
