Small Triad

Hi,

Does anyone have any idea why my Triad has gone small? It's still active, if I roll over it I can move parts in the X, Y, Z axis or rotate about X, Y, Z but it's difficult to see which one you are on & extremely difficult to pick the one you want.

This is what I get if I right click a part & select move with Triad:

This is what I get in an exploded view when I select a part to explode:

No matter what zoom level the Triad stays the same size on screen.....very small.

I've looked through the settings & couldn't see anything to change it.

Update:

This issue seems to only happen on some assemblies. If I open a sub assembly from the one giving issues & try to move a part with Triad, everything looks normal as below.
