1. What is the issue? Please be detailed.

When loading a form on ODK Collect, I get the error node for itemset doesn't exist! [instance(color)/root/item/label]. See the attached screenshot for reference. This error appears to be caused by applying the parameter randomize=true to a select multiple question in a multiple-language form. See attached form. Removing either the parameter or the extra language columns solves the issue. The form loads with no errors on enketo.

2. What steps can we take to reproduce this issue?

  1. Upload the attached sample form to a project in https://ona.io or ODK Central
  2. Download the form on ODK Collect
  3. Load the form for data collection

3. What have you tried to fix the issue?

  1. I removed the extra language columns, and the form loaded fine on ODK Collect
  2. I removed the parameter randomize=true applied to a select_multiple question and the form loaded fine on ODK Collect

4. Upload any forms or screenshots you can share publicly below.
