• [x] check removing calculation - issue does not occur so likely not caused by relevant
• [x] check removing relevant - haha, also does not occur, so it's some kind of interaction between calc and relevant

I cannot think of any use case where it makes sense to have a calculation on an autocomplete widget, so I am inclined to not spend time on this.

Looks like expected behavior to me. The calculation is re-run and evaluates to '' because neither none nor other is selected. I think this is similar to https://github.com/enketo/enketo-core/issues/880#issuecomment-1101038570. If you'd like a dynamic default you can use something like https://docs.getodk.org/form-logic/#dynamic-defaults-from-form-data. Calculations may be re-evaluated at any time.
