2D extras, ruletile not working

Hello all!
I am using Unity 2019.4.9f1 under linux. I've tried adding the 2D extras package from github, and I can but the rule tile I create doesn't work properly.

I can set the rules, then drag & drop the rule tile asset into a tilepalette and draw with it but the rules will not apply, only the default sprite is drawn.

I've downloaded this version according to my unity version https://github.com/Unity-Technologies/2d-extras/releases/tag/1.5.0-preview
Extracted it into my Assets/Packages so now it is there under the folder
2d-extras-1.5.0-preview

I've added a manifest.json to my project as written in the github repo, it's under Assets/Packages/manifest.json

It's contents are the following

Code (JSON):

1. {
2.     "name": "com.unity.2d.tilemap.extras",
3.     "version": "1.5.0-preview",
4.     "displayName": "Package Example",
5.     "description": "This is an example package",
6.     "unity": "2019.4",
7.     "author": {
8.       "url": "https://github.com/Unity-Technologies/2d-extras.git#master"
9.     }
10. }

So everything seems to be working properly I can create rule tiles I can't see any dependency issue or anything like that, simply the rule tiling won't work

Any help would be much appreciated!

 

Solved, my rules were set wrong...
