Congratulations on your purchase and welcome to the forum!
An easy fix would be just to change the labels around and learn to live with it.
I don't know what your faucet looks like, but it might be as easy as switching the pipes under the cabinet. (Probably need hubby for that). Take a look in the cabinet under the faucet and see if the red line is connected to the left side of the faucet and the blue line to the right.
If those are correct, then you might have a bad cartridge in the faucets.
