SELECTING BOX EDGES OR MOVING SUBS ISSUE

I'm having a strange issue where trying to move subs on the enclosure or selecting anything on the box is completely off.

For example, if I try and click on a sub to move it, it wont select it. I will have to click around off the box to try and find where the software thinks the sub is to be able to move it.

Same thing if I am trying to select box edges.

Please help!
