Just realized the name is correct in the app, but on the website it's wrong.

Small error in place name, "Maalahti" in Finland should be "Malax"

(The naming convention in bilingual Finland being that the majority language in a given region is used internationally. Malax is the Swedish language majority name of the municipality. Maalahti is the correct name in Finnish, but is only used in a Finnish language context.)

The correct name Malax can be seen on the topographic map that is displayed when zooming further in. But on the grey windy map it is wrong.

Other place names in the same area seem to correctly use the Swedish name primarily in Windy.
