Macro Keyboard - Same Keys?

[MorbidNature]

 So I've recently bought 2 wireless numpads to work as wireless macropads.

First works great, but the second one has a little "bug" to it. (bought 2 different types for different uses)

 

The 3 of the top row keys which are the " ( " key, the " ) " key, and the $ key all conflict with each other which i try to reassign them in HIDmacro as if they were the same key - but in normal use, they work just fine.

There is a "Del" key also in that row that works perfectly fine when reassign.

 

 

 

I'm assuming it something is the hardware they remapped something or other.

Question is it something i can get around or just leave those 3 keys alone (the rest of the numpad works fine)
