Portals putting you out incorrectly

It is so annoying as I lost full netherite gear and tools on my way to fight the ender dragon for the 3rd time as it out me at my over world coordinates in the end and as portals are low y levels it instantly put me in the void. It's the same with the nether and I doesnt create a new portal to go back through to the over world your just stuck there please get it fixed I dont want anyone else to lose all there gear to this
