Hi user_5359!

It's ok to delete if you find one because they are errors that come with mapwithai data, but always can be fixed automatically in the validation panel (JOSM) when you run validation.

We are sorry that you find them uploaded in OSM and thank you for reaching out, we will make sure that all validation warnings solved before uploading!.

Hello, @user_5359, Key conn is just like a dupe, it's an error that comes from Mapwithai data, it can be fixed automatically too, again thanks to @mueschel for fixing the problem.

Hello, @user_5359 thanks for reaching out. Key dupe is an error that comes from Mapwithai data during the importation of highways to the OSM layer. It can be fixed automatically in the validation panel, it won't happen again. Thanks, @mueschel for fixing the problem.
