Like I've told you before there is a trivial solution to the problem you were having. Unity has the concept of "Pixels Per Unit" that is used for textures, sprites and tilemaps. SuperTiled2Unity also supports this functionality. All you need to do is make sure you are using the same "Pixels Per Unit" value for your Tiled maps and tilesets.
By default, Unity prefers values of 100 because that works well with their 2D physics systems. Personally, I use a value of 1 so that 1 unit is 1 pixel. YMMV.
If the issue persists then report a bug on my GitHub page and I will look at it further.
