Reference levels not updating

I have models that are referenced into other models within the same file. However when the levels are altered in the raw model the reference will not update unless I delete and re-reference the model back in. Updating levels within the reference manager doesn't work. Any advice?

On another note I have a sheet view with a large set of boarder references from an external source. However when I turn the ones I don't need off and save settings/save the document, then close and re-open the document, all the references are all turned back on. Again any advice?
