Okay I have noticed something in regards to this issue. When I played another account, from scratch, the issue only occurred when I was taking Hutt Contracts and not playing the associated add-on DLC only. Any Hutt Contract I took while playing only with the add-on DLC it was associated with seemed to keep this issue from happening, and only if it was not already having an issue.
What this means is Hutt Contracts associated with the Bespin add-on DLC only seemed to add correctly when playing the Bespin add-on DLC ONLY. Same thing is true for the Outer Rim add-on DLC, only the Hutt Contracts for Outer Rim add-on DLC seem to add correctly when playing the Outer Rim add-on DLC ONLY. Don't know about the Death Star add-on DLC as I haven't played much on that. Well that is how it's been so far on that other account.
One other important thing I noticed if you already got the issue occurring on a certain hutt contract, it DID NOT seem to correct itself when playing the associated add-on DLC Only (it still had issues not adding correctly but seemed to at least take less time to finally complete the contract when compared to my main account). So once you pick a Hutt Contract stick with the associated DLC until it is finished.
