Remote garage door opener

Weird issue with programming remote garage door opener. I purchased a 2022 CX9 Grand Touring used at 22K+. I successfully program the left button to open the left garage door. However, after I program the second one for the right garage door. The first one is no longer working. I see a yellow blinking light instead of green blinking light. If I reprogram the 1st one. The second one, again, yellow blinking light instead of green blinking.
Any ideas?
