That’s strange, I’m not easily able to reproduce it, for me the column count stays the same across all sections… it might have something to do with the length of the user information in that section? Either way, on closer inspection I think the flexibility of this layout can be improved to avoid leaving what looks like an empty column at some widths
that’s not the greatest, and can be improved to better fill the space… not a very high priority change, but I can look at updating this when I have time
