2015 Revo 13 rudder control issue (RESOLVED- operator error)

I got a new to me 2015 revo 13 this winter.  I was out in Humboldt Bay this morning and put it through its paces in an area with strong current.  I had an issue come up with the sailing rudder where it wouldn't stay fully deployed after executing a hard right turn.  I would have to pull on the down cable to get it back into the water. 

This is the first time that I tried making hard turns at speed in a current, but I was able to recreate this problem every single time.  It didn't have a problem on left turns.  It was definitely tippy on hard left turns at speed but the secondary stability is good.  On the right turns I couldn't get it to get to that point without the rudder coming up.

Is there a simple adjustment somewhere to make the rudder behave itself?  Sorry if this is a dumb question but I'm new to mirage drives, hobies, rudders, and the like.

Thanks.

Lock the rudder "Down" handle in. That may help.

is it clipped in?

Ok found it.

I'm dumb. I was looking all over for sonewhere to clip the line and must have had my leg resting on it.

There are two online owners manual videos that is very helpful. I'm not one to go over manuals myself but the videos are short and very insightful. You should check it out.
