Form field value shows [Object object]

I am a first time Mautic user. A new Contact based on a web form is not being added to the correct segment. I am using the campaign builder with a condition based upon a Form Field Value. I select a custom form field but the values populated in the form show [Object object]. This is particularly unexpected as when using the field in a Contact Field Value the value is correctly populated. I have tried to replace the [Object object] with the correct form value but it didn’t help.



Does anyone have any thoughts? Is the [Object object] likely to be the reason why I can’t add the user to the correct segment?



The only thing shown in the log is:
