Power table text sometimes whiting out?

I have a power table with a boolean column that is selectable.

Sometimes, when the boolean column is selecting, it changes the text color to white and I am not sure why. Like this -

My configureCell extension script is only the the following -

return {'background': 'white'}

I have an on mouse press event but it just updates the dataset to rememer the boolean selecte, nothing to do with any text color properties…

I do not have any bindings to foreground color or any Appearance properties on this power table.

Is this a known issue bug? Ive searched the entire window for references to foreground, color, text, and cannot find anything that could explain this.
