Field changes criteria in the start event of an advanced workflow

Hi,

I have created an advanced workflow where a field change should trigger a task to be created, however, it isn't working.

The workflow works without this criteria, as well as with criteria that aren't the three field changing ones (changes, changes to, changes from). Is there something I am missing here, or are there any known bugs with these criteria? I am using them on a dropdown field.

I am using Sugar version 7.9.1.0

Thanks.
