Description
This version of ALM Toolkit reports differences due to mis alignment of Source to Target comparison. For columns, it will show a difference but in reality its just in a different location within the BIM. It will be the same for partitions, showing a difference but in reality its comparing 2 different partitions instead of comparing itself to the same partition.
For the partitions, this started for me after install 5.1.3 and then adding additional partitions & renaming some existing partitions.
I have deployed the source to the target, and the differences are still reported. Additionally, I used TE3 to deploy BIM files from source to target. I re ran ALM toolkit and it still reports a difference. I am not sure why it would show a difference when the BIM files are identical.

Research direction
Start by reproducing the comparison with the described columns and partitions after renaming and adding partitions, then verify the source and target BIM files are identical. Done means ALM Toolkit matches columns and partitions by identity rather than position and reports no differences for identical models.
