Attribute Text Height

I'm trying to update the text height of a few different attributes, but the changes I'm trying to make are not being saved. I'm trying to change the height from 1/8" to 3/16". However, when I change the height in the text box, select a different attribute value, and then return to the originally modified value, the changes have reverted. When I try to use the point-to-point method, the results remain as long as I have the Advanced Attribute Edit box open, but they also revert as soon as I press the OK button. I've checked for similar options and tried the "UPDATEBLOCKATTRIBUTES," but with no change to the results. Is there something in my settings that is preventing this to change or is this just a bug?
