When deleteing a way, if it's in a relation, the position numbers don't match

[rickmastfan67]

When doing some license change cleanup, I had to recently delete a way because it was completely tainted. When I did that, since it was part of a relation, I got the message asking me to confirm that I wanted to delete it from the relation. When that message showed up, I noticed that the "Position" number for the way inside of the relation didn't match in the popup window and in the properties.

I've attached a screenshot showing this.

This problem is easy to duplicate (as long as there is more than 2 ways/nodes in said relation). Every time, the position numbers are off by 1.
