Received ITA - will a mistake in work history dates be a problem?

[LittleGray]

Hi everyone, I received my ITA for STEM category with CRS of 494. While I was filling out the PR application, I noticed that I made a mistake in my work history dates for my Express Entry profile.

My real work history of 3 jobs, totalling > 2 years of work experience:

1. 2021/07 to 2022/06
2. 2022/06 to 2022/08 (correct dates)
3. 2022/09 to now.

For the 2nd job, I mistakenly put the wrong year in my EE profile: 2021/06 to 2021/08 (incorrect dates). While I corrected this mistake in my PR application, I was worried whether it would be impacted by the mistake. It seems to me that it shouldn't matter because my CRS score would not change even if I removed this experience from my profile/application.

Should I be worried? I am thinking of explaining the case in my letter of explanation. Maybe that would help?

Many thanks in advance.
