What is the cause of this issue?

A developer created a custom metadata profile and assigned default values to some fields. The developer applied this custom profile to a folder in the DAM that already uses a different metadata profile. When viewing the metadata properties of the existing assets in a subfolder, the developer noticed that the custom metadata profile was not applied to these assets.

What is the cause of this issue?
A . The contents are cached and clearing the browser cache should resolve this issue.
B . The new metadata profile will only be applied to new assets that will be added to the folder later.
C . The custom metadata profile has some invalid field values and is preventing it from being applied to a folder.
D . The new metadata profile will only be applied to assets that are direct children of the folder.

Answer: B
