I tried both removing all beacons and removing only the beacon I just placed. I run into an issue most times where the game will not allow me to place a beacon anywhere on Koboh. That happens 90% of the time. The other 10% it actually allows me to place one on the current map, I remove it/all, goto the Galaxy map, then back to the game.
From there I will have approximately 2-5 seconds where my lightsaber can hit enemies, force powers work on enemies or the environment, Marrins Charm works, and now what I have discovered wall running.
After that brief time, none of the above works on enemies or the environment.
For the 90% of the time the game doesnt allow me to place a beacon on Koboh, I will goto the Galaxy map, select another planet, place a beacon there then remove all. The end result is the same 2-5 seconds of abilities working.
