While I haven't used 9.2 (newby using 9.3) the usual reason for this in 9.3 is the lack of a breadboard group in the svg. The svg export function is the only thing I know of that this affects. You might try (in an svg editor such as Inkscape) edit->select all (to select the whole drawing) then object->group to make a new group and change the group id to breadboard (which will at least in Inkscape rename the current breadboard id if it exists) and try that and see if it fixes it.
