Subscription types description error

Using OJS

When editing the description part of the Subscription types, the previous information is not removed. This is an example of where I wanted to removed the “$100 + $10.00 shipping …”, but when I edit the subscription type, no description is visible.

Institutional Subscription (US Dollar) - Online only
$100 + $10.00 shipping and handling

Not sure if this is a bug or I am not doing something right using the script editor. Maybe related to older error: OJS 3.1.0 Subscription Types Description
