When I edit an item which does not have label and description in one language, its item label and description are disappeared (see the below attachment)
I use this item https://www.wikidata.org/wiki/Q912184 as the example in the screenshot.
These are the steps to reproduce the bug:
- Go to https://www.wikidata.org/wiki/Q912184
- Change your default language to "British English"
- Click the "edit" button in the term box
- Click the "cancel" button
- Afterwards, you will see that the label and description are gone
