Thanks David, I understand this, but I don't think this should be happening. The default should change depending on the setting of the view you are selecting. Example, if you click on a floor plan with the existing reno filter, it changes the default to existing. Then if you click on a plan with the new filter, it changes back to that. Right now it only seems to go one way.
Or maybe the default filter should not change at all, it should only change if you change it manually.
Graphisoft knows this should not happen (it changing without you changing it manually) but have yet to fix it.
