You can force the misbehaving columns to behave - more or less: the M
value on the 17th will cause problems (btw, I prefer
to have a non-exported "zeroth" column for things like / and !
that are basically table metadata - see (info "(org) Advanced features")
for details):

The misbehaviour is caused by the heuristic used in
org-export-table-cell-alignment:

,----
| Return alignment as specified by the last alignment cookie in the
| same column as TABLE-CELL.  If no such cookie is found, a default
| alignment value will be deduced from fraction of numbers in the
| column (see `org-table-number-fraction' for more information).
`----

You can play around with org-table-number-fraction (default: 0.5) to
change the behaviour. A value of 0.25 will right-align them all, whereas
a value of 0.75 will left-align them all. But I wouldn't want to bet my
life on that: it depends on the contents of the table so it seems like a
fragile solution at best.

BTW, the 0.25 and 0.75 values above are purely trial-and-error (actually
derived from the smallest ratio I found edebugging over the columns:
6/21).

Footnotes:

[fn:1] The heuristic counts empty cells as numbers if the non-empty row
       above it is a number, so for the first column for example, there
       are 21 cells and 11 of them are "numbers".
