This is a very common problem that most people face when making homemade pasta. Myself included. You will want to add additional flour on to the dough if it’s feeling on the sticky/moist side. Then knead the dough a little bit and let it rest for 5-10 minutes longer. I have found that by adding more flour to help dry it out a little and kneading it again and letting it rest is the ticket. I will cover the “faulty” piece and start with a new piece of dough while the other rests.
