Problem description

Filled values in a required question (new circumference) in Trees Create or Update form get removed after tapping "check for errors” or trying to send the form. It seems that it happens when the circumference field was left empty in registration form.

Steps to reproduce the problem

1. Download user "createORupdate” https://staging.getodk.cloud/#/projects/101/app-users.
2. Go to trees registration space1 form and create an entity with species but WITHOUT any value in circumference.
3. Go to Trees Create or Update form and select the created entity.
4. Swipe to following questions (don’t change prefilled choices/selects), in "new circumference” enter a number.
5. Tap the three dots -check for errors or try to send the form (the filled "new circumference is removed – there’s information that the response is required)

Expected behavior

Filled values shouldn't disappear

Other information

I tried to reproduce it in Trees update form but the issue doesn't occur.

I think this is a mistake in the form right? new_circumference ("New circumference") has is bound with a calculate on the current circumference of the selected tree being updated so when "Check for errors" happens it'll get calculated again. Unless I'm mistaken, this form should be using trigger (https://docs.getodk.org/form-logic/#dynamic-defaults-from-form-data).
