[Help][Visio] I can't apply line-end to connector

[kompilator.malam]

I am newbie for Visio, I want to add an arrowhead as line-end to my connector. But, it doesn't work. FYI, I use UML activity metric, I have changed it to US unit, but still, it doesn't work.

Solved.
It caused by because I didn't choose new Drawing at beginning, but choose new Software and Database --> UML Activity.
