I would appreciate if someone could clarify this feature:

Delete Old Reward Transactions Period
Set the age (in days) to keep the reward point transactions. Outstanding reward points pending after this period will be lost. Set to 0 to keep all transactions.

Is this mean that any points that are earned will not be deleted no matter what? I setup this module using Sunrise Period of 1 so pending points become earned the next day but I like these earned points to be deleted after 30 days but looks like the system doesn't delete earned points?

Below is my setup and any input would be appreciated.
