Sentence form

[JackLovesEng]

Hello, teacher
I've been trying to figure out if the form of the following sentence is correct.
"They should've changed the order from right to left"
This sentence was originally related to a commercial where things should've been placed from right to left and the advertisement had them from left to right (,which shouldn't be the case because it was for middle-eastern countries and that's not the correct order for reading stuff there.)
So my question is, shouldn't the question be something like "they should've changed the order from left-to-right to right-to-left"?
The original statement somehow doesn't sound correct to me.
Looking forward to your answer, and many thanks for helping us out!

I agree! The original statements does not make sense.
