I am working in QGIS 3.4, and trying to merge 10 polygon shapefiles into a single shapefile. However, the result is not preserving the values for most of the shapefiles, it's NULL-ing them out for all but one of the shapefiles.
- Must the exact number of fields exist for all 10 shapefiles?
- If so, must the fields be ordered exactly the same for all 10 shapefiles?
- Must the fields be named the same for all 10 shapefiles?
