I opened my pen and tried to fix it myself, it worked but it didn't solve the problem, still every 5 minutes the ghost touch comes back, if I press the pen a little bit it goes back to normal, it's kind of annoying but I manage to do my job. the problem is when I paint subtle things, like shadows, I can't see when the problem comes back, so it's very difficult, almost impossible to paint (with sanity). so I'm only going to do the flats colors for the pages in the first half of the month, until the new pen arrives. then I can finish the pages normally.
