I am using a ui-select field in my Magento 2 admin form. The dropdown fetches data via AJAX on search and correctly displays options. However, I'm facing an issue:

First search: Options load correctly, and I can select one without any problems.

After clearing the search and searching again: The new options appear correctly, but when I select an option, the field displays: "Entity with ID: ... doesn't exist"

After this issue appears, any further selection also shows the same message, instead of displaying the correct label.

I have explained the issue in detail here: https://magento.stackexchange.com/questions/376462/magento-2-ui-select-entity-with-id-doesnt-exist-after-searching-again
