Bug in Node numbering when grades added from Gallery

Steps to reproduce:
1. Create a power grade that consists of a single node (regular or compound)
2. Create a Resolve 17.2.2 project
3. Make sure "Preserve node numbers" is checked in the preferences
4. Create a grade with three nodes
5. Drag your power grade from the Gallery onto node two
Expected outcome: Node numbers remain the same
Actual outcome: Node 2's number changes to 3 (and 3 changes to 2)
