Revision history [back]

This is happening because you have Comments in your OSM file, and it's safe to ignore. I guess the Warn should really not happen for comments (here) but I'm not enclined to change it myself right now (open a github issue if you care)

anyways, in your file, first occurs around line 4958

Looks like some manual editing happened in your file, or maybe a conflict resolution of some kind.
