Trying to remove line on asphalt textures

hi, i am trying to remove the line on the center of asphalt foundations. It is driving me nuts... Other then working myself through the tutorial mod from the documentation i have no experience modding satisfactory. So far i have used FMod to check the texture files. Using the ficsit textures as reference, it should be the left edge of the top half causing the issue. But i have not really found anything clearly causing it, in any of the texture files. I also compared the ramp _BC file, as the line is not present on ramps, but the difference is really small if there at all. Are there other places, apart from the texture file, that would be worth a look for finding the cause? And am I correct with my assumption, that it would be the left edge, top half of the texture? (if yes, i might try and modify the texture slightly, to see if it makes any difference).
