MouseMove's Java Robot Class Does Not Match the Specified Location

Question

Honestly, I'm not quite sure what is wrong. This is a short version of a ton of other basic robot team movements under if and if else.

Whenever I run the program, the mouse should go to the designated position and click. However, when I run the program, it does not move to the position indicated by me, instead, it moves to a different position each time I launch it (I do not have listeners assigned to change the position so that the position does not change). I don’t know if this is something with code that I wrote myself or perhaps my import? The program worked correctly until recently, when I added else to the end to finish the program, I started it without the rest and still ran into the same problem. Any help would be greatly appreciated.
