As far as I remember, it is a nice name. Actually its meaning is fantastic by paying attention to its meaning which is related to Allah. Of course it has some different definitions such as:
Ablator, ablative, resolver, soarer, but anyhow, on the whole, its meaning is positive.
But seemingly you are confused and sad due to its meaning which is related to Allah.
In accordance with some narrations, it is better not to choose some names of Allah for children, such as:
Hakim, Malek, Nafe' and so on, but the point is that at majority of times, people who call other people, do not pay attention to the main meaning of their names, in fact their purposes are solely the individuals who are calling. (Not the name of Allah).
According to a narration:
it is Makruh to name children from the names(Sefaat) of Allah. (but it
doesn’t mean it is Haram).

So as far as I know, a way which can help you, is putting the word "Abd" at the first of those similar names. How come?
For instance, one of my friends' name is Rahman, but we call him Abdol-Rahman, hence I reckon at least you'd better put the word Abd at the first of his name.
Of course it could be better if you change its name in his I'd card as well. But anyway, as I mentioned, at least you can call him Abdol-Rafay.
