How can I get support on Trendy?

I have a many trend on the MathWorks Tredy page, and also many plots there. But I have a problem with this plot: Rank for J.R.!

And I suppose that there is an error in the web page code, not on my matlab code, because when I click on the "Regenerate plot" link, the plot looks well again, but it stil appears the error: Error using href="matlab:helpUtils.errorDocCallback('circshift')" style="font-weight:bold">circshift</a Invalid shift type: must be a real finite integer vector.

I also could not find the way to contact "someone" to help directly on Trendy.

J.R.!
