I included form 8962 in my 1040-X, IRS is requesting form 8962 in a letter again

Weeks ago, I filed form 1040-X to amand my 2023 tax return. A corrected form 8962 was included along with form 1040-X. 

Today I got a letter from the IRS, it says "We're unable to correct your account with the information you provided on your Form 1040-X, Amended U.S. Individual Income Tax Return. Please provide the following: A completed form 8962 to support the changes you made."

I'm confused since I already included form 8962 in my amendment package.

Anyone had similar issue?

Thank you!
