This path (Lemmerersteig) is out of use and dangerous: the marking has mostly disappeared, the rest of the path is very narrow and steep. Wood trunks and stones fallen from a nearby cliff obstruct the way. 
It would be better not to indicate this path at all on the map, as only people who know the area very well and are used to the mountains would be safe on it.
Reference: I was there 30/05/2021 and witnessed myself.
