This is why having multiple coaches teaching jumps causes problems. One coach likes one landing position and another a different one; one teachs one type of entry, a different one a different type of entry ... unless the coaches have a similar style, it can be very difficult for a kid to work with.
I would discuss the mixed messages with her base freeskate coach and then let the base freeskate coach fix it or not based on the way the base freeskate coach wants the jumps executed. Generally, coaches value a soft, deep knee bend, and will point out the depth of knee on ice-dancers when they are trying to get their freeskaters to use their knees well and "skate into" rather than "skate on" the ice.
My kid used to get chased around the ice practicing depth of knee and edges, and is wayyyy underbooted (by most peoples standards) so that we have a deep, soft knee on landing; as a result, there is less wear and tear on the knee and hip and back, and landings can be "held" even when a bit wonky.
