You have two X theme licenses. One was purchased last Jan. 07, 2016 and the other was in June 21, 2016. Both of your X theme were upgraded to Pro theme last Dec. 27, 2018 and Jan. 03, 2019. Now if you are validating Pro theme, please use the Pro licenses. If you are still using the X theme, then you will have to use the X theme license code.
Hope this helps.
