I think I found the source of all the confusion.

The village was referred to as Eidskrem in some maps until 1992, but the d was a typo. This typo then ended up on some signs, some of which have been replaced and some have not. See this news article explaining it all: https://www.rbnett.no/nyheter/i/m1yOOO/derfor-heter-det-eiskrem-og-ikke-eidskrem-som-det-star-pa-skiltet

I've reverted your change here. I hope it isn't too discouraging. I know you made this change with good intentions.
