What is it with my Platinum card Spending Power not even for 3k?? I don’t even owe that on my card 😠😠

I was trying to make a purchase of $2700 and the card didn’t go through. (Embarrassing) I was checking my spending power which it was above $50,000 and now I cannot even get approved for $3000? even though I don’t even have a minimum payment coming up because I keep making payments one or two times a week??

What are your thoughts on this? Thank you all !!
