Xbox One writing book glitch

Hi,

I've had this happen on a couple of Sims now. I am playing on Xbox One.

When writing books, the Sims sometimes leave the book unfinished and go and do something else. When I go back to resume writing the book they go to the computer, get annoyed or in some cases do nothing, then the resume book disappears from their queue. it seems the book becomes corrupted and is forever there under resume writing but can never be finished. 

My latest Sim has two such books. There seems to be no way to get rid of these corrupted books and I'm stuck with them forever appearing. I'm not sure if there's a limit to how many books can be in the resume writing list, but if there is, my worry is that my Sim will reach this number and he'll no longer be able to write at all.

Anyone else experienced this or have any ideas why it's happening or if there's a way I can clear the list?

Many thanks 

Traci.
