Just click on an Enemy Node on a farther way path, then click the revealed Path Tile. So for this path for example click on the Ms Marvel Kamala Khan which will shrink that Juggernaut and Gamora Image blocking your way, then the Path Tile for Mole Man and Sabretooth will be easily clickable. It's annoying but this has been a thing happening for a Long Time, you'll get used to it...
P.S: I would like to see a guy who is doing a legend run, and losses half a hour just trying to click this buttons.
