Issue with scala backticks in pattern matching

I have two sealed abstract classes,A and B and their subclasses. I am trying to use them in pattern matching as:

(a,b) match {
   case (`a1`, `b1`) => ....
}

a1,a2...b1,b2.... are subtypes of A,B respectively.

while IDE(Intellij) can detect a1, but it is unable to detect b1. All imports are defined well.

Is it wrong way of using back ticks?

a1 a2 b1 b2 are instances of the subclases or the name of the subclass, can you put a larger example with the instanciation of a1 and b1? – Alfilercio Mar 15 '22 at 12:23

Also, are the clases of a b a1 etc case classes? – Alfilercio Mar 15 '22 at 12:23
And what error you get with the code – Alfilercio Mar 15 '22 at 12:24

Have you tried binding the vars like case ```(v1 : `a1`, v2 : `b1`) ``` ? – ccheneson Mar 15 '22 at 15:21
