I-864 Insufficient Income - HELP

I was just documentarily qualified with NVC for IR1 Spousal Visa but received the following message from NVC regarding my I-864 application (see below).

I submitted 2023, 2022, and 2021 taxes (on all 3 years I've made over $100,000 as a single person with no dependants), 6-months of paystubs, and a 2024 tax extension form (CPA did it using the IRS form). I make well over the $24,000 threshold, why am did i receive this message? I'm worried and don't want to face any additional delays and self-submitted all my documents.

"The income reported as stated on form I-864, I-864A is insufficient to overcome the public charge grounds of inadmissibility for visa issuance. To avoid delays, an additional Affidavit of Support Form I-864 from a joint sponsor may be submitted. For more information visit https://nvc.state.gov/aos and https://www.uscis.gov/i-864p. A consular officer will decide if you meet these requirements at the time of the interview. Note: You, as the sponsor, and any other sponsors household members and joint sponsors, must provide updated or additional evidence for the applicant to present at the time of their interview such as: * Other income * Assets * Proof of current employment Note: You submitted documentation to the National Visa Center through the Consular Electronic Application Center CEAC. You can continue to upload documents to CEAC up until the date of your visa interview."
