Bedrock Beta bug with the new purple wood fences

Im in a pure survival world on the Bedrock beta version. I collected the crimson wood from the nether and ended up making some fencing. I made a fence gate, thats where the problem began. I made 1 gate, placed it down and didnt like it. i destroyed it and picked it back up this made the fence gate an infinite amount. It shows that i have 1 gate but i can place down as many as id like. But if i break them theyll dissapear; so i can place multiple from 1 gate but it doesnt drop after that. I tried this with regular wooden gates. It did not seem to have the same problem; it never turned into an infinite source. I havent gotten any of the blue wood yet so i dont know it those are bugged as well. This has only ever happened to me so far with the crimson wooden fence gate. To find a video click this link- https://twitter.com/DarthTrans/status/1242188465309089793?s=20
