Wrong last repetition date

Problem

I got this error:

 Wrong last repetition date
 Element:  8
 Date:  7/6/2024
 Today: 7/1/2024

What does it mean?

Answer

While repairing a collection, SuperMemo discovered an element whose last repetition "took place in the future".

In your case, Element #8 is marked as last repeated on July 6, while the detection occurred on July 1 (5 days earlier).

This error may result from serious integrity problems in the collection (e.g. change to the "first day of the process" value). It may also be a result of a single error in a single record (e.g. due to playing with the date in your computer, etc.).
