The problem is that the footprint you have chosen is incorrectly constructed. It has numbered bottom layer pads superimposed with unnumbered Multilayer pads.  The Schematic symbol is OK but poorly constructed in terms of it being unclear and unconventionally drawn. I have created a new Schematic Symbol and PCB Footprint for you to try: TMC2208\_SILENTSTEPSTICK\_EVAL\_BRD [https://easyeda.com/component/61f522d71d724baf88ca8ba94811e026](https://easyeda.com/component/61f522d71d724baf88ca8ba94811e026) They are the same dimensions as the ones in your schematic so you should just be able to swap the Schematic Symbol and the do Update PCB to pull in the new PCB Footprint.

Andy, it worked beautifully! My nightmare is over :).  That probably also explais why I was loosing the Net names in this component each time I updated the PCB from the schematics. Thank you for taking the time of redoing the component, it's awewsom and I appreciate it. It's my first week with easyeda and pcb design and I was really lost.

It took a bit of detective work to get to the problem but I'm glad I was able to resolve the problem.

@andyfierman Hi Andy , I read  with attention  your reply to  Dany because I got his same problem. But  the difference is that I developed the pad ( led 3535 Z5M2 Seoul) and  only  on the cathode I got the problem. this is strange,  the construction methode is the same of the anode. I made a thin track hoping to solve but nothing. do you have any suggestion/trick? I made other led cases ( 2835 / 1616 )  and I never got this kind of problem thanks in advance 

@andyfierman I solved the problem, making again the led pad. I don't  know why but making the first time the pad I discovered there was another pad inside, the red one you can  see!  this pad made a system conflict  ( clearance)
