Bucket: integer (input) vs float (output) when exporting data (CSV/JSON/ARFF)

Hi, when inputting integer type numeric data (declared as internal in the source code) to the bucket, everything seems to go well when viewing them in the grid (see attached image).

However, when exporting data to CSV, integer type numeric data is presented as float type (see image below).

Is this a bug? Or is it related to how the Database stores this numerical data? When exporting the data as ARFF file, I identified that the database classifies the column as “numeric” (see images below).

If it’s not a bug, how do I get Thinger.io to store the data as integer types to export to CSV correctly?

Correct. Numeric data are presented as integers:

Incorrect. Numeric data is exported as a float
CSV:

ARFF:
