External antenna selection issue in Particle DEV any suggestions?

Can someone help ?
Up until today had no issues with macro selecting external Wifi antenna. Today for unknown reason


Produces following error:

It looks like you have a Core selected. The antenna select isn’t available on the Core since it has only one antenna.
