Metadata dropdown takes too long to update due to large response payload

[priya-tik]

In the Events tab, when navigating to the Metadata section and modifying a drop-down field (e.g., Series), the selected value is updated correctly. However, the update takes unusually long.

Steps to Reproduce:

Go to the Events tab.

Open the Metadata tab for any event.

Change a drop-down field (e.g., Series) to another option.

Click Save.

Observe the delay in updating the value.

What I observed:

The selected value is saved correctly.

But under Network → Request, the API returns the entire list of available options (e.g., all series in the collection array) even though only the selected value is relevant.

This leads to a large payload and performance lag.

A potential fix has been submitted in [PR #1235] titled "Fix clean metadata". It aims to reduce the response payload by sending only essential metadata fields (like id and value) during updates.
