Stuck progressing my Jedi Knight's storyline

There are have been multiple reports of this issue happening on different classes as well and has been filed in the bug reports section as a player on their bounty hunter had the same issue:

There are several bugs such as missing companions, missing affection / influence, etc.  You can submit a bug report for your companion as well as an in-game ticket to see if they can resolve it however due to the number of in-game tickets it can take several days for a response.

More then likely if they post any updates on it, it will be posted here in the dev tracker:

I had this same problem, and after a little peek at the forum I saw someone else say they'd had a similar situation and been told to reset their story quest. I tried that, and it worked perfectly. It should fix your issue too.

It wont let me reset storyline

Try resetting on fleet

Nice necro. This post is over a year old... And the fix at the time has already been posted.
