ISOLATE DRAWING LAYERS

I created two layers using the sketch name as a search rule. They are *ORI* & *EC* two layers respectively.

The model tree has the ORI_SKETCH Feature and the drawing has an Original Design view using the isolate 00001_FOR_PTC_CASE_ORI  layer setting.
When the ORI_SKETCH feature name is changed to EC_SKETCH and the 00001_FOR_PTC_CASE_ORI & 00001_FOR_PTC_CASE_EC layers are updated
Finally the "Design Changes" view and the "Original Design" view are not updated.

I have to reset the layer isolate before it updates.
