I will recap my steps:
I imported a LS product: LC082040312017110601T1-SC20200511135125.tar.gz (using optical sensors, Landsat, 30m resolution function). Then a subset for the region of interest. After a re-projection to WGS:
Then I did a vector import of ESRI shapefiles (created in the original subset image without reprojection):
Then ML classifier and no results again
