"Reposition Camera" can't change axis.

[Goldmes]

As specified by the hint, you should be able to "Hold Square to change the axis." But my camera is still stuck at the same axis with or without holding that key (that's it, D-up & D-Down for vertical movement, and D-left & D-right for only single-axis horizontal movement).

Tho, while unspecified, the Cross (X) button works for speeding up the translation.
