Proposed cross section not merging with existing cross sections

Good morning All,

I'm having a problem getting the "Merge Cross Sections" tool to work correctly.

I have both existing and proposed cross sections cut and residing in their proper model views.

The merge tool recognizes the proposed cross sections source and I deselect the layers I don't want to be merged and then select "Process", but nothing gets copied over.

Any help would be greatly appreciated.
