Eye of Enders leading to nothing instead of Stronghold

I've been playing Minecraft for a while, soon I located a stronghold right? I updated to 1.11.4, I wasn't ready to go to the end to fight the ender dragon yet, so once I was ready, I started using the eye of Enders to get to the end to fight the ender dragon, once I located the stronghold, I dug down, and down, there was nothing at all. I tried again the other way to the other stronghold, still nothing. I was extremely confused why I wasn't able to find any stronghold. The previous stronghold in the previous update had a stronghold but why didn't update 1.11.4 have one? I would really want Monjang to make it so that eye of Enders don't lead to nothing, it would be great and very helpful.
