Actually, the name of items (columns, tables, etc.) is essential for the Update from database process.
Currently the name is the most important component when comparing items.
Because of that when two columns have different names (even if they are almost the same) they are considered different.
As you can imagine, we cannot know with 100% accuracy which column has been renamed to which other column, and what was the intention of the user.
This is why in the Update from database wizard a pair of add / remove operations is shown.
The best we could do here is a suggestion that a column has been renamed, but ultimately it is up to the user to decide.
We have some plans to improve the experience in that area, but I cannot share anything specific at the moment.
As always, your feedback is most welcome.
