Can confirm, relates to MC-270062.
Note that the command provided has a small issue, the first letter of "Ominous" should not be capitalized.
You may have misunderstood what I mean, the issue I linked is about the same buggy behavior (ominous vault created by players can be only opened with normal trial key instead of ominous trial key) in Java Edition.
I think Mojang needs to make it easier to get the ominous vault. If they could just add the item to the creative inventory it would make mapmaker's lives a whole lot easier. This bug is terrible.
For the builder looking to circumvent this limitation, I just attached a .mcstructure file. It contains the original vault data inside. So, If you create a behavior pack, then put this mcstructure on "structures" folder, you can use /structure load ominous_vault ~ ~ ~ to spawn a functional ominous vault, or use a structure block and load "ominous_vault"
