The Bible alters the spellings of peoples names many many times in the Bible but yet we know it is speaking of that person based on the context or by comparing Scripture with Scripture.
Jehoram just has an "eh" added to Joram. It's the same person. This is not uncommon to see in the Bible. Abram became Abraham. Noah is referred to as Noe in the New Testament. Elijah is referred to as Elias. Isaiah is referred to as Esaias.
