Opening an archive, I double-clicked on the "Name" column to expand it since the file names were long, but that made the column disappear.
I tried right clicking and looked for any options and searched the web but I can't seem to be able to find a way to recover the disappeared column. Closing the application as well as restarting doesn't affect this.
Note, I have indicator-appmenu uninstalled. Could it be that the archive manager is supposed to have a menu that I'm not able to see because of this? (I see the menu on every other application).
This is how the archive manager looks like right now:
The "Properties" field refers to the properties of the archive, not the archive manager.

Get your cursor to the left hand side so that is is 2 arrows pointing left and right. I made a screenshot with the column nearly gone:
Just drag the cursor to the right to make the column larger.
The following command resets the margin width for file name in file-roller:
