Bug - OTP (email) and No Duplicates

Bug - OTP (email) and No Duplicates

Scenario:
  1. Form with an email field, Validation: "No Duplicates" (because I want to ensure 1 entry per email).
  2. Embedded form into website (JS option).
  3. Enabled email based OTP.
  4. 1st test (via my website) - entered my email address - sent OTP - entered pin, form appeared - excellent!
  5. Refreshed page, OTP request again.
  6. 2nd test (via my website) - entered my email address - received error: "No duplicate values allowed for this field"
I understand the instructions note, "The selected field's validation properties will be applied on the OTP Verification page as well" but surely, a duplicate email address for OTP purposes doesn't apply until at least the form was completed / submitted, not an OTP request alone (this is why I think of this a bug rather than by design). 

In my opinion the "No Duplicates" should not apply to OTP or at the very least, I would want the option for OTP to bypass the "No Duplicates" option because sometimes a user may want to see the form to read the instructions on the form, but not submit a new response.

I know I could possibly (haven't tried) create an additional email field for OTP purposes, hide it, however from a user perspective it's not the best experience - they shouldn't need to key in their email address again if they've done it for OTP purposes.

If there was the ability to set field values based on rules then I could achieve this, however this is also not possible per https://help.zoho.com/portal/en/community/topic/is-it-possible-to-set-a-value-to-a-field-based-on-certain-conditions
