[Bug] Rename of entities not correctly taken into account

[albaintor]

Is there an existing issue for this?

• I have searched the existing issues

Description

When I rename an entity from the ui pages or from activity screen, it is not always correctly applied.
I found the culprit after making a backup and open it : when I open the activities/uc.main.XXX.json file, there are 2 names, one for english and one for my language (french here) and both are not the same. It is unclear which one is displayed but it is also unclear why one can define a different name per language whereas it is not possible to set up from the UI
{"entity_id":"uc.main.1267279d-3195-4b50-a719-a087dbeae315","entity_type":"activity","integration_id":"uc.main","name":{"en":"Regarder TV Orange","fr":"Regarder TV Orange IP"}...

How to Reproduce

Not systematic : rename an activity then go to a page where is it is displayed.
The old name is still displayed

Expected behavior

The new name should be displayed every pages where the entity is added.

UI version

1.6.1
