Surface mapping on flat surface not really working as I hoped

So I am trying to map this path on a unrolled surface, but somehow it only does this mapping over the y axis and not over x it just makes it very wide, tried a lot of things but im really getting stuck here… any ideas what’s going wrong? See file with internalised objects
