Baud Rate on nRF52 issues

Hi, I am evaluating two nRF52832 boards with a PCA10040. I am using the SDK examples Central and Peripheral to talk to each other on Tera Term. I am using the "send file" operation on tera term. On this file, I have typed six characters (all numbers). So I am trying to see how the UARTs on both boards work and the details in which they talk to each other. For this, I have been trying to communicate at different baud rates with the same message. I have connected an O-scope to the boards to see what gets sent and what gets received. The first picture is the send and receive of the UARTs at baud rate = 9600. The second and third pictures are the same message but at baud rate = 912600. As you can see, at the 9600 rate, the message is send and received normally. But at the 912600 rate, the received looks broken up and really weird. I have also tried it at baud rate = 38400, and it works fine as well. Can someone explain what exactly is actually happening at baud rate = 912600 and why it doesn't send/receive data properly? *note: 3rd picture is slightly scaled out compared to 2nd picture so you could see how its broken up.
