Text Styles not holding when inbeded in symbols

[MattG]

Is this a operator error or a possible bug. I am going through some of my lighting fixture symbols and thinking it would be nice if I had all the text inside the symbols match. I decided to attempt to have all the text on the same "text style" and then if I decide to alter the appearance be it font, color, text styling or what have you I can do it semi globaly. However I am finding that when I am doing this I can select the text choose my text style from the drop down and the text takes on its attributes but the drop down reverts back to the select text style. Then if I edit the text style the supposedly assigned text does not respond.

What do you guys think?
