DATAIKU APPENDING DATA ITSELF

Hi,

I am using an CSV data in my flow an my data duplicates itself after many plugins and data appends itself (DOES NOT OVERWRITE) when i Run Fuzzy Join with strict equality steps.

Also I have used a demo data (CSV file) before and I changed it now, however i still see same data from demo in every plugin, (Clear data action also do not work)

I really seek your help, thanks!
