I removed duplicate polygons in Alteryx.
However, some of the adjacent parts of the duplicate polygons remained in a line shape and could not be completely deleted.
I have attached the WF. I need you to solve the trouble.
In the WF, I am trying to delete duplicate street polygons at the borders of Japanese prefectures.
However, it is not possible to delete them cleanly.

Have you tried adding a buffer to the line before using it to remove the overlap?
Thank you for your reply!

I would like to understand how to add a buffer more.
What should I introduce the algorithm and add tools in this WF?
Thanks for your cooperation in advance.
I took some time to understand what you were trying to achieve and I believe I found the issue. You need to remove the overlap with the opposite PREF polygon. And I also had to use the buffer to increase the size of the polygon by 0.01324km (13.24m) to remove all instances where there was still an overlap. I reached this number by trying different values, this is the most precise I got.
