Mine is review required because I couldn't provide a reference letter at the time of submission (e-APR) for my foreign experience (provided later in Nov 2021) and my reference letter from Canada was signed digitally. Strange thing is that the Case Processing Agent marked this letter unsigned and kept this under review too. My score dropped some 100 points due to this. I guess they don't count the experience requiring review while assessing CRS.
I suggest you get a reference letter from your employer ASAP. Follow the requirements. Paraphrase the duties for your NOC code. Get it signed and dated on the company letterhead clearly mentioning all the company and the issuing authority's details. You can already submit this one using case-specific inquiry via WebForm mentioning that you came to know this from GCMS notes. If you receive an ADR in meantime, even better. You just submit again on the portal.
Note that they don't accept letters that do not have duties mentioned, because then they can't confirm your NOC code you used while applying for PR.
