Hi alain2003, 
I noticed you uploaded on the OSM server a huge number of unconnected nodes while you edited the boundaries, addition you uploaded that with unavailable Sources and this Didn't follow the OSM policy
there is the OSM policy link: https://blog.openstreetmap.org/2017/03/17/use-of-cc-by-data/
Please check this big error and revert all changesets that contain this error.
there are some changesets: 
https://www.openstreetmap.org/changeset/159055395
https://www.openstreetmap.org/changeset/15905540
and If you will update the boundaries please upload them with an available and official source. 
Have a nice day and happy mapping!
regrets
