Error in program rule: accidental archiving computed age of tracker program in data element used in data entry (aggregate)

Greetings,
Using dhis2 2.3, for tracker capture.
The form includes tracked entity attribute: tea_cv_birth date (date format)
In attempt to compute age, an error has occurred: setting a program rule where age is computed and archived in another data element called de_cv_age.
But this data element was already in use as number format in data entry (aggregate).
Since then, the program is not working well. The event report is showing empty tables, the event import is missing files.
I will be thankful if you can assist
