So here's what I've noticed... and the steps to reproduce it.
When I import a model and perform either a rotation (in x, y or z... doesn't matter) or if I change the
model's scaling factor (either uniform or non-uniform) all of the transform values on the GUI reset
to their default values regardless of the transform input sequence.
I did notice however that the transforms are kept in the GUI's undo queue so reverting to the value
of the last transform is possible (but if you go back into the undo queue and then change any transform
value, the same scenario as described above occurs).
@S3D Team: Can you folks please take a look at this and include it in the next update?
