Everything in bundles has been deleted

I had a bunch of items in bundles, normal thing to do right, well bedrock said no, I came back a few days later to find everything in said bundles gone, no where in sight, although the bundle I had in my inventory was not affected, nor was anyone else I knew, and worst thing yet, I had netherite, diamonds, and a nertherite upgrade template in them, all I can really say, is check you bundles before it is too late!
