Question: How to stop Maple from adding new variables to differentiated equations

Hey,

I'm trying to differentiate a function but whenever I do so, it adds new variables for some reason. I think I might be able to copy the new function and just delete the extra but it is not a good solution.

 

So I'm hoping someone could help me to figure out how to remove all this extra that Maple adds to my equation. Thanks in advance.
