I had similar issues a while back and have started to notice it again recently with the "Also Add Characters When Adding Words" setting.
I have this unitcked so it should not add the characters individually when learning words, however, I am in the process of trying to learn definitions and writing a tonne of cheng yu's (成语)and for some reason it has started to add words individually and it becomes a pain in the butt.
Has anyone else had the same problems?
Also is there anything the Skritter guys can do to check fi there is a bug here or if there is something in my settings that is causing this.
Thanks all
