The skill card “Gateway to the Another Dimension” doesn’t work

YGO Omega Bugs

It works now.
However, there are three bugs now.

  1. When I send the xyz monsters from EX to GY, all the level of monsters on the field become level one.
    >>> the level should become the same as the rank of the xyz monsters you send to GY.

  2. I can only active the skill once.
    >>> should be able to active it once per turn. (and no limit times per duel.)

  3. " If you send a monster to your graveyard from your Deck, you can send 1 monster to your Graveyard from your hand. "
    I can not do it correctly from hand to GY.
    It shows hint “ask for sending cards to GY”.
    However, after I click “YES” and choose what card I want to send. It does nothing.
