Offer for this player pending

I have been trying to get Mbappe for a long time, but every time I tried, his agent would basically say that I don't have enough reputation to get him. I tried a few times every transfer window until, eventually, when I reached 94 reputation in 2023, I was able to even place a bid ($165M). After I got through that, I was still being told by the agent that he is not interested but that he can arrange a meeting. I paid the coins to set up the meeting. I had everything in order, but then a popup came from my board that told me, "You already have an offer for this player pending." The worst part about the popup was that it wouldn't go away when I pressed back. I had to force close the app. I was able to get past the popup, but I still couldn't offer Mbappe a contract. I went through this same process with KDB a few seasons earlier with no hiccups. Granted, it was my first time offering any bid for KDB. Despite my several attempts to get Mbappe, I never had any pending offer for him. What am I to do?
