When you use a custom field text multi-line clear value post function, the history record from the issue shows strange values like the clod ID and the custom field ID in the old issue view.
- Create a text multi-line custom field
- Add a post-function to clear the value in a transition
- See the history record in the old issue view
The History record should not have any value just the clear event
It is adding some IDs to history when seeing it in the old issue view
Use the new issue view
