problem in gambit
 

I am using Gambit to model a reactor. While drawing the injector, I wanted to move it to its right place in the reactor, but each time I am trying to do, Gambit tells me that: "Error: the entity cannot be transformed due to it being connected to another entity or having higher topology" despite I am not connetcting it to any other entity!!! thanks for help.
