When I execute a cell in jupyterlab, it says that it's executing 2 cells (shown in this photo). I don't know what the second cell is. The first cell will finish, but jupyter will say that it's busy processing the second cell. As far as I can tell, the processing time of the second/phantom cell isn't related to the processing time of the first/actual cell: sometimes it takes about the same amount of time, sometimes it takes (a lot) longer. This gets especially annoying while I'm trying to execute multiple cells consecutively. Something that should take a minute ends up taking 10. Does anyone know what's causing the problem and how to fix it? I've tried updating anaconda and reinstalling it. Both attempts were unsuccessful.
