Help regarding walls and borders(?)

[windy10]

heya, i never expected to see myself posting on here when most of the questions i wanted to ask were already answered, but here i am regardless

so, in a test project im working on, im trying to create a "border" effect along the walls, as shown in the screenshot below, courtesy of yume nikki and yume 2kki. circled is the part im talking about




i made myself a few borders to test it out, but came across a problem.



while filling the map up, i realized i couldn't get the border to end on the sides of the door i made, and i've been trying to figure out how to fix that all day to no avail.

does anyone have any clues or solutions to this problem? ive experimented with countless self-realized methods, but came to nothing, and some help would be greatly appreciated ^^


EDIT: added some more images to give a more in-depth look into the problem, the autotiles seem to act weird around certain areas upon placing lower-layer tiles or other autotiles around those places

UPDATE: solution found(?)

by putting a black tile from the upper layer over the autotile, you can effectively "remove" it.
to make this look neat, an extra tile may need to be made to correspond with the black tile, but this may just be an alternative to the real solution since it still has different behaviors compared to the screenshots.

help is still appreciated

UPDATE 2: doesn't work well. looking for the original method.

upon using this process listed above, the tiles may look weird or abnormal.

Press Shift+right click on a black tile on the map, hold shift and press left click in the tiles you want to adjust.

Shift mapping is the way in this cases.
