Change in localized text not captured

[raul-ruiz-acn]

Hello
I have an entity with a localized description but i am not able to capture the changes to these descriptions.

Let me share some details just in case they can help. My entity has several fields: some of them are just normal attributes but description is localized to allow different languages:

entity Products: managed, cuid { code: ProductCode @mandatory @assert.unique; description: localized ProductDescription ; cold: Boolean ; threshold: Integer ;

I added the change log annotation to track changes:
annotate ProductService.Products with @title: 'Products' @changelog: [code ] { description @changelog; cold @changelog; threshold @changelog;

This services is used in a fiori elements app that allows the user maintain the product attributes as well as the different translations:

As far as I can see I am not missing anything (at least i cannot find in documentation) so i guess it might be a bug.
Thanks in advance for your support
