"Total records in imported data aggregates with old imported data"
Hello, I am relatively new to RapidMiner. I am using the Rosette extension for text mining. I have imported a number of practice datasets to see how the various text mining algorithms work. The problem I am having is, whenever I import a new CSV file, no matter how I import it, the data somehow aggregates or combines with prior data. For example, I had one dataset with 1035 records. Later, I imported a dataset with only 100 records in it and it shows up with 1135 records. Is there a step in the import process that is causing all of my data to accumulate in this unwanted fashion?
