You can confirm the processing version of Shikisai products by the following site.
  https://shikisai.jaxa.jp/cgi-bin/ver_hist/ver_hist.cgi?lang=E

The product version is different depending on the observation date because of the version upgrade and the reprocessing. You can confirm which version and which period was processed for each product.
In the version history, there are places where multiple versions overlap in the same observation month. Please refer to the below diagram.

① in the below diagram: Due to switching between version upgrades. However, there is no duplication of products with the same observation date and time.
② in the below diagram: Due to reprocessing due to the version upgrade. The old version will be deleted after the latest version completes processing. (There is an overlap of publication for several months)
