Cells' outputs getting appended at each run - Databricks Notebook

[TheoLoiseau]

Hello Community,

I have the following issue. 
When I am running cells from a notebook, I have the print outputs from the previous cells that are appended to the current print output (meaning running cell 1 gives output 1, running cell 2 gives output 1 + 2).
I am on Microsoft Edge for Business, version 121.0.2277.83 (64-bit).

Anyone having the same issue?
Thanks a lot,

Theo

P.S. these are print outputs that are replicated from cells to cells.

Another issue spotted with my context, is that seaborn's heatmap function is super slow (running for 6 minutes and still not finished)
