Hello, how are you group, I need your help, I have a question… 🧐

I had a pending order to buy 5,000 #XLM at a price of 0.2768….

After hours it was completed correctly, but I am confused about the following…. Why does it show that I bought my 5,000 #XLM at 0.3561 when I actually bought them at 0.2768 NOT at 0.3561?

Could someone explain to me why this happens? Thank you 🙏
