Updated_at not changing after updating fileupload field

Hello.
I’m using several content types in my project, by defining them in their respective Tailor blueprints. The problem is, when I upload a file through the UI, for a fileupload field, the “updated_at” field is not automatically updated, as it usually happens with other types of fields.

I’m on version 3.5.14.

Any clues?

Thanks in advance for your comments.
