I ran into this with my e3v2 a LOT. Are you heating up the bed and nozzle before you level? You may have answered that and I missed it. Also, I’m not sure how well those silicon things work, I did the “yellow springs” and then make them all equally tight, then level by loosening. Another thing to check- is your build surface flat? Check when cold and hot. My glass bed wound up warping up near the middle ever so slightly and that would be enough to make a batch of moms spaghetti. I was able to get it working well for a while, then it somehow shit its pants into the silicone sock and mucked up the whole hotend with nice black pla+.
