I'm not an expert on double jumps - can't even do a proper single - but I think you have presented insufficient data.
But we can't really see the details of the blades themselves - e.g., whether the rocker profile is weird (and significant weirdness can be on the scale of hundredths or thousandths of an inch), or they are worn out, because there isn't enough metal left, a less well defined or differently positioned sweet spot, edges that are asymmetric, etc. Nor can we see what was done to modify the footbed, or have any idea what she needs in that way.
She might even just need to get used to the difference in boots and blades.
At the very least, people might need to see a detailed video of her jumping, slowed down, along with her impressions of what is happening. E.g., maybe she is expecting the toe pick to touch at a slightly different time than the current one does.
It is also a question that a good coach familiar with your DD might be able to answer in person better than we can.
You can partly deal with the difference in horizontal offset, if that is a problem, by putting tape under the insole in such a position as to make it feel better balanced.
