After Greencard

Hi guys, I just receive a second notice of action from my finger prints, my case was already transferred from California to NBC back in December, I honestly don't know what is going on or what does this mean. Is anybody with the same experience please share, again my case is in California (WAC) and this second notice of action came from California. This second notice didn't appear in my online status by the way, It's still in the transferred action
here is my time frame:

01/30/2020 We received your Form I-751, Petition to Remove Conditions on Residence.

06/08/2020 On June 8, 2020, your request to change your address, referral number CA......., was assigned to an officer for response.

06/09/2020 On June 9, 2020, we sent a response to your request to change your address, referral number CA.....

06/09/2020 On June 9, 2020, your request to change your address, referral number CA......, was completed

09/11/2020 The fingerprints relating to your Form I-751 Petition to Remove Conditions on Residence, were taken

12/22/2020 Your Form I-751, Petition to Remove Conditions on Residence, was transferred to another USCIS office

On December 23, 2020, we transferred your Form I-751, Petition to Remove Conditions on Residence, Receipt Number WAC209xxxxxx, to another USCIS office. That office now has jurisdiction over your case

01/28/2021 just got on the mail the same exact notice from my finger prints but with the date of 01/22/2021.... I'm so confused now, my online status did not change at all, it is still on the transferred date on 12/23/2020

please share any similar experiences or if you guys know that I have to contact them at all
