Chase reduced my limit on both cards

So I had 2 Chase credit cards (Freedom Unlimited & Sapphire Preferred) that got charged off 4 years ago due to some heavy financial strain. 2 years later, when I was buying my house, I hired a credit repair company , they removed them, and to my surprise they never came back.
A month after closing I opened a Chase checking account, and to my surprise they offered me the Freedom Unlimited ($4K limit) and Sapphire Preferred ($5K limit), which I accepted.
My balances were always decent until the past couple months where they’ve been really high. I had one returned payment by accident, truly an accident 😭 which I guess triggered a review. I had just made a $2K payment on each card, and I got a notice from Chase that they reduced my limit on both cards by $1,400.
Now I want to pay the cards off but I’m scared that if I make another big payment they’ll keep reducing my limits. 😭
