dev.mod - Celery - some multi instance models are not working

[madhurrya]

These models are not working as expected in dev.mod. It's working as expected in dev.app

1. When the Continue button is clicked it goes to waiting state instead of showing the next Continue button.

2. When I run this model in dev.app https://dev.app.spiff.status.im/process-models/misc:qa:bpmn-model-testing:unit-test-multi-instance-parallel-user-task-input-collection in the end instructions it shows the 3 colors I typed. But when I run it in dev.mod it only shows the last color.
