Hi, I do you have multipolygons in your input files? If not, perhaps the multipolygon is being created because both polygon have the same ID, A. Try creating a unique id field to see what is going on. A multipolygon or multipart object will contain multiple polygons but only one data line in the data table. You can split multipolygon with a «multiple to single »tool found in the vector menu.
