Disappearing Parentheses

I think we must have something set incorrectly in our Options. I would be grateful if you could help me determine exactly what it is.

When we specify a standard fit on a diameter dimension - e.g. 4H7 - we like to add the actual tolerance values in parentheses.

Thus, the note looks roughly like this: 4H7(+0.012/0).

A better example is shown in the attached jpg.

Our problem is that we add the parentheses and they disappear before our eyes. They are there for about half a second, then they disappear.

Any idea why this would happen?

Thanks,
