Conditional Field is showing the wrong options in the field it is referencing

Hi. I am inside of a field set. I have a grid that I am attempting to make conditional so that it displays when a separate pulldown selector field equals one of its values. For example, the pulldown has the values cat, dog, or mouse. If mouse, I want the grid to display. However when I am building the condition using the tools provided under the “make conditional” option, the values it serves for the field I choose are not cat, dog, mouse. They are pizza, bread, tea (which is a totally different field’s values). I never swapped the fields or renamed them. I also cleared cache and reindexed. Is this a bug? Thanks
