The label is supposed to be empty. See https://github.com/bitcoin/bitcoin/blob/master/src/qt/forms/coincontroldialog.ui#L444
It was empty before, dont know which change let appear the "1" there and why, seems weird.
This is a linux only bug. I assume setting a empty string or even a 1 char whitespace (" ") could fix this issue. @wtogami: mind creating a fix for this?
Win/OSX OK:

Linux/Ubuntu NOK:

Not only. For reproducing on Windows simple compile with Qt 4.8.6. I think it is a Qt4 bug...
