I have seen this a couple of times, including my own dog. Let me begin with my own story:
Today one of my evil cats, one of many, was doing someting...evil. We usually yell at them by making a hissing sound and/or clapping. As I was doing this, Hunter leaps up and runs to my side, slightly lunging forward as if ready to "defend the pack".
This is usually a natural reaction in most dogs. They will defend who they deem their leader in either disciplining or defending. Sounds like Mayzie is following Ranger, but may not know how to react when alone or has picked up the "offish" attitude toward dogs from Ranger. This is when you need to take the innitiative.
I would start by closely observing her. Start taking her for walks where dogs might be, keep a safe distance, but watch her reactions closely so that you can learn when/if she stiffens, makes too much eye contact, if the tail raises, if the hair on the back of the neck and back raises. These can be signs of trouble.
I'm not sure how you discipline/your training method, but I would correct this behavior as soon as it becomes apparant that her attitude is changing for the worse towards another dog.
I'm sorry if this was too vague but I'm not sure of your training methods, and my method (dog psychology, close to what Cesar Millan uses) is frowned upon in this forum, so I don't want to overstep my bounds if you do not use this method.
I really hope that you can figure this out or someone will be more helpful to you.
