I remember that there was a similar case but not when and if there was a solution. At first I would try to display these values by right-clicking on the description field and fully expand the following columns instead of clicking on the single-icons. Another approach would be to recreate this table from the scratch in case that this table is corrupted in any way.
ps: also an upgrade to a recent release might be helpful.
Something very similar happened to me - we were using 2 different SR's of QV 11.20 and passing the qvw made tiny bits corrupted. Not sure if this is the case here, but probably the best idea would be to re-create the object.
