Temporarily Unlock Landscape actors in level?

I’m relatively new to UE4, currently using World Machine to generate some addon landscape features such as hills and mountains. But I noticed every time I wish to move my landscape actor, I need to manually right-click > transform> uncheck Lock Actor Movement. After moving my landscape in only ONE action ie. move it to the right, it gets locked again and I need to manually unlock it every time. Is there a way to disable this ‘auto-lock’ feature?? I know it’s there to prevent me from accidentally moving my landscape but I need to rearrange my landscape actors often. Help?

Anyone? Is it impossible?

I am having the same problem since 4.13
