Frame's and Lead knots glitch

Once I updated my world from 19w04b to 19w05a it was all normal, then randomly, after loading my world a couple of times, my item frames disappeared, then a little later whenever I try to lead something to a fence, it would fly through the sky, but disappear after a couple blocks (but they'd still be lead to the fence I put them on... but the lead was invisible, but also connected to, as I found out, the lead knot in the pic) and I ddin't find this out until walking around my village and seeing these.. floating... and I can't break them, survival, creative, nothing. And idk how to remove them, but they wont go away, and I can't lead anything without it bugging out lol

(I'd like to add that, the item frames have the right items in them, except for one which has 2 swords in it, maybe a friend of mine added one to the frame by accident? And the frames are in seemingly random locations too)
