Not sure about everyone but when you try to manually change ch with your keyboard you bump into this problem.
But say if I press esc followed by clicking on change ch and the number of the ch I seem to have no issues. I can also press esc then hit enter and then click the ch and still have no issues. I can also click the ch that I want and then hit enter and it still works. Tell us if that works for you though, it might sound kinda jumbled or confusing.
edit: for some reason while I was double checking myself I stopped having the cc bug, hope some people can help me double check on this.
