I wonder if "that needs to be addressed" is modifying "a potential distraction" or "offices"

In a recent employers’ survey a wide variety of computer functions have/has been identified as a potential distraction in offices that needs to be addressed.

I’m confused here whether the modifier "that needs to be addressed" is modifying "a potential distraction" or "offices". in my view, it seems most likely that it’s modifying "a potential distraction".
Is this just an acceptable way that I don’t need to seize on? Do native speakers also happen to get confused by a sentence like this? but they can identify which noun is being modified depending on context?
