ATC Error In Demo

I don't know if this has been mentioned before.I was making an IFR flight this evening using the Bombardier CRJ in the demo, and after one set of instructions, the choices never appeared. ATC kept asking if I'd heard the transmission, then cancelled my clearance. As soon as it was cancelled, the choices reappeared, I opened the plan again and was able to keep going (until time ran out...)Just bringing it up :)
