If you load a map, go Options->Mod settings->Map and modify values, then click apply, nothing will be changed. If you reopen mod settings, the values are what they originally where.

(You can change the settings from the main menu, but they don't effect existing save files)

If you click apply and then exit and re-open the menu without going back to game they haven't been applied yet because the game is still paused.

o, i see, thanks. A bit odd it works that way
