[V8i .NET] Element Tags Value as string with \1 issue

I am using Element tags for storing file paths, however, I am noticing that  \ followed by a number is causing some strange issues.

For example with \1

".\Rice Road\CAM\Camera 1\160527_000930896_Camera_1.jpg"

becomes

".\Rice Road\CAM\Camera 1 527_000930896_Camera_1.jpg"

                    Dim currTag As TagElement = ele.AddTag(tagDef)
                    currTag.IsHidden = tagDef.IsHidden
                    currTag.Value = filePath

I am stepping through with the debugger and can see that filePath is fine and currTag.Value is getting jumbled.

Any ideas on what is going on?
