Visio For EA - database diagram - bold text for Req'd columns is not working properly

All--

Please help.

I have "Visio For Enterprise Architects (11.4301.6568)".

I have database diagram.

The bold text for Req'd columns is not working properly.

That is...

For some Req'd columns, the text IS bold-- which is the visual cue that shows at-a-glance whether or not a given column is required.

That is good. That is what it is supposed to do. That is what looks nice. Excellent.

...BUT...

For some other Req'd columns, (for no discernable reason), the text IS NOT bold.

Ug.

That is not good.

Is there a way to fix this

Please advise.

Note that the file in question was created in "Visio For Enterprise Architects SP-2 (10.0.5110)" and then opened in "Visio For Enterprise Architects (11.4301.6568)". I think that is the root of the problem because it seems that the use-bold-text-for-required-columns rule is enforced for all columns that existed before the conversion and for all columns that have been added after the conversion the rule is not applied. It would be nice if the rule were consistently applied or not, rather than a mish-mash.

Thank you.
