Requested operation coldn't be completed in Symbology setting
I am trying to duplicate a line symbol layer when editing one of my symbology classes, but for some reason it doesn't let me copy the layer by showing "Requested operation could not be completed" on top of the pane.
A few backgrounds on the things that is involved in this symbology setting. It classifies feature by unique value. However, instead of using one attribute in the feature class, the unique values were calculated using expression builder.
I enabled symbol property connections as part of my task, but thinking this may have been the reason why I couldn't duplicate line layer, I have turned it off ever since.
I did the same thing back and forth with "Symbol Layer Drawing" as well, but it didn't seem to make any difference.
I was able to copy solid stroke layer when I was editing the first symbology class named I-405. Then I did bunch of other editing before coming back to "I-405 Ramp" class, but I couldn't recall which step is the turning point that makes this operation incompletable.
