On the primary facts edit interface of a tv page, you just have to change "TV Show Type" field from Scripted to Miniseries.

If the field is locked ( ), you can use the "Report" button to let us know it has to be changed. I'm assuming you want mark Stanley H. as a miniseries, I just unlocked the TV Show Type.

@Rebecca Thanks. I'll try that.

@banana_girl Thank you so much. Changed to mini-series!

I locked it back with miniseries as the type!
