Subject: Optional Fields Select field is defaulting to first option even with no default set

Description:

I’m trying to use an Optional Field as a required drop‑down on the quote/checkout form, but I need it to not default to any option so the customer is forced to make a choice.

Per the Optional Fields and Custom Questions documentation:

- Optional fields “can have default values to start with.”

- For Select (drop‑down) fields, I can:

- Define options separated by commas

- Set a Default Value (or leave it blank)

- Mark the field as “Required on Page” so it’s required to save the lead or get a quote

However, even when I do not set a Default Value, the Select field is still loading with the first option automatically selected.

Steps to Reproduce:

1. Go to Settings → Optional Fields

URL: https://rental.software/account/#/settings/optionalfields

2. Create or edit an Optional Field:

- Type: Select (drop‑down)

- Options: add multiple options separated by commas

- Default Value: leave this blank

- Under Quote Form, add it to a quote/checkout page and set Required on Page = Yes (so it’s required to get a quote / check out).

3. Save the field.

4. Go to the quote/checkout page where this field is shown.

Actual Behavior:

- The Select field appears with one of the options (typically the first) already selected, even though no Default Value is set.

- Because it’s already selected, the customer can proceed without changing it, even though the field is “Required on Page.”

Expected/Desired Behavior:

- Ability for a Select Optional Field that is marked Required on Page to:

- Load with no option pre‑selected (no default), so

- The customer must actively choose an option before they can complete the quote/checkout.

If this behavior is not currently supported, this is a feature request for a “no pre‑selected option” state on required Select-type Optional Fields.

Here is one example with screen shots but all three questions in the screen shot i want to be this way.
