Packing List Fields Not Updating After Discard Confirmation

[uwebury]

Hello,

I am currently working on my Form component and I am experiencing a non-rendering issue that I don't understand. It seems to be related to the fact that in component there is a .map that is not being rendered again after the user confirms discard: "Yes, discard please."

Other (non-array) fields such as destination show their original data as stored in MongoDB.

I have committed and pushed my current status. It is accessible at this link. The branch is called 'feat/packing-list-part1'.
Here is also a link to the deployed feature branch on Vercel.

How can one reproduce this issue?

1. On homepage, click on one of the cards. (Or create one yourself yourself for testing purposes using the Create button '+').
2. On DetailsPage ([id]/index.js) of the card, click 'Edit'.
3. Edit the content in the fields, focus on the ones under 'Packing List'.
4. Click on 'Discard' button --> Toast message appears: 'Are you sure to discard all changes?'
5. Click on 'Yes, discard please.' --> Toast message appears: 'Form reset to last saved version.'
6. Except the entries in 'Packing List' fields, all fields are restored to last saved version.
7. Reload page will also update 'Packing List' fields.

What is expected to be happening?
After confirming discard ('Are you sure to discard all changes?') all fields should show the content as stored in MongoDB. So the user should see the same content before their changes.

What should be considered?
The fields from 'Packing list' are coming from an array. (The other fields are not.) That's why we assume that the .map is not happening after confirming to discard all changes.

What we already have tried so far?
We have already looked at it with the whole team and each member has tried different ideas on how to fix this. We also researched on re-rendering array data but our attempts did not work as wished. We also have factored 'PackingList' component back into the form since we hoped this might help us to fix this.

Thank you for your help!
