3 strongholds, no end portal

So, on the Xbox One Edition, I already had an end portal. Now it is no longer there once I uploaded to the new version. Fine. But now I have found 3 strongholds within a 4000 block radius and none of them have end portals. Very frustrating. This is too time consuming to walk 4000 blocks in 3 directions just to be let down when I had already found it in my previous version.
