leaking boxed wine?

Is boxed wine leaking from the spigot common?

I have a boxed wine in the refrigerator but it looks like it’s leaked a glass worth of wine over the course of a day. It has a twist-type spigot. I’ve thought about standing on end to stop the dripping but my guess is that it won’t be airtight anymore if I do so.

I figured it out… the spigot has a lock when you twist it. It just isn’t immediately obvious.
