The whole process is working fine. But there is one field that is not being filled when creating a Lead.
(the screenshots are translated since the orginial is in hebrew)
Created custom field to capture the selection

Set the mapping field to the one in Lead

On the form submission I can see that the field has value

The lead is created properly and all the fields are filled but this field remains empty

On the Audit History I get this strange Icon

The field on the list has the type OptionSet
Thanks, any help will be appreciated
