Multiple ender dragons on switch version

Multiple ender dragons keep spawning in the end. Every time I enter the end portal they keep multiplying. I now get killed almost instantly after entering. Very frustrating spending hours on a survival world getting supplies to fight the ender dragon and not being able to finish the game! I have seen posts of this bug from 7 months ago. With all due respect how is this not being fixed. Paid for a game that has a bug that prevents you from winning, I have no ability from my switch to attach files. This is my first post so I don't know if you guys can respond.
