How to change my gig's Included Revisions value?

[shape7]

From the gig’s settings I find this box:

But whenever I change the value of the Included Revisions dropdown-menu and hit Save, nothing happens. The Save button does not do anything! The Save button works on the other pages of the settings menu, but not on this one. Does the save button on that page work for anyone else?

Help me! I can’t change and save how many revisions are included in my gig! I’m a Level 1 seller, if that matters.

I think it is a system’s glitch.Contact with customer support and ask them to resolve this issue.
