Cleans up data that is not required when using Anki’s built-in FSRS support.

What type of this data? Related to what?

When FSRS was not integrated into Anki, FSRS required custom data to work. Now that it is built into Anki, FSRS doesn’t require custom data. This option allows the user to clear that old data (if they used FSRS when it was not integrated).

Is running this option in the Helper how I would get rid of this outdated information in the card info?

Yes, you got it right.
