default value for whole number custom fields does not display or save

[TanyaStere42]

Expected Behavior

When a sighting is reported, the default value is saved unless a different value is provided by the user. Clearing the value is respected unless it is a required field.

Current Behavior

1. As admin, create a custom sighting field that is a whole number with a default value
2. Go to report sightings
3. look at custom sighting field; will not have default value
4. submit sighting
5. go to sighting
6. sighting will not have value in the whole number custom sighting

Additional test information - contributor test

Assume custom sighting field with default value is already created

1. Log in as contributor
2. Individual contribution Create a sighting as per usual.
3. Fill in all the fields and hit submit.
4. FE requests : /pending-sightings/{sightingGuid) which is not visible to the contributor user on the BE. FE should just show a "Thankyou" message for contributor created sightings

QA Verification

• report a sighting without changing default value; verify default value is saved on the sighting
• report a sighting and change the default value; verify your changed value is saved on the sighting
• report a sighting with the default value on a required sighting field. clear the field; the sighting is blocked from being created
• report a sighting with the default value on a non-required sighting field. clear the field. verify the field has no value saved on the sighting
