Unstable Dimension Extension Text placement

Below are two dimensions, both requiring placement of the text extended to one side of the dimension. On the left the text has been node-dragged where necessary for legibility. On the right the text is at the default distance. I find that with opening and closing and otherwise working with files, Rhino will revert to the default distance, which has happened to the dimension on the right. (I realize these are two different dimension styles, but this reversion happens within same styles – I don’t have before and after examples of that at the moment. I have given up custom spacing because of this, and this is difficult in many cases as the below example demonstrates.)

This issue was present in October. Is it a known bug now? If so has it become resolved?
