Multi site - wrong status when checking different site

[B1nk1e]

We have a multi-site setup with multiple languages and use this plugin to manage assets. Some assets are connected to just one site, while others are used across multiple sites.

Here's the issue we discovered:

If an asset is used on Site ID 1, when we check the asset usage on Site 1, it correctly shows where it's being used. However, if we check the same asset while checking a different site (with a different site ID), it shows as not being used. This is problematic because if we proceed to clean up assets based on the information from this other site, we might accidentally delete the asset, even though it is actually being used on Site ID 1.

This could lead to important assets being removed unintentionally from sites where they are still needed. Ideally there would be something it's used on what sites.
