OLC - How to hide "What you'll learn" value showing to learner

Summary:

Wanted to hide "What you'll learn" value showing to learner which is provided by Learn admin at the time of creating Course for "Short description" field.

Content (please ensure you mask any confidential information):

We renamed short description field name to Alert preference.

We are using the Alert Preference field value for alerts as an alert triggering criteria and that's the reason we renamed "short description" field name to "Alert preference".

So when learn admin enters the value for "Alert preference" field which is "short description" field, that value is showing to learner under "What you'll learn" when they access the course also when tried to enroll to course.
