Can't move trace to top of board


I have two traces on a pcb that I have drawn that won’t let me move them from the bottom of the board to the top - I can’t see anything specific about these two traces (others can be moved). I am using the latest release on mac. The traces in question run from the tx/rx pins of an ESP8266 to the appropriate pins of a max232 chip



Where can I find the ESP8266? It looks like that part is causing the issue.
You could try to edit it in the parts editor and see if it has connections available in both layers.
