Not able to change assets(video) once uploaded in document

Hi Everyone ,

Not able to change assets(video) once uploaded in document using(Resource Compound Field).

I created a new document type and added a resource(Compound Field) field to upload video assets . Video is getting uploaded only once. Once uploaded if I want to change it than it is not changing , when I click to change it it is showing download option.

Is there any possible way to change the asset(video) when required.
