Very strange bug: [[MyrkulLordOfBones]] somehow see an instant card [[Gridlock]] by creature filter

Myrkul, Lord of Bones - (Gatherer) (Scryfall) (EDHREC)

{4}{W}{B}{G} Legendary Creature — God 7/5 As long as your life total is less than or equal to half your starting life total, Myrkul, Lord of Bones has indestructible. Whenever another nontoken creature you control dies, you may exile it. If you do, create a token that's a copy of that card, except it's an enchantment and loses all other card types.

Gridlock - (Gatherer) (Scryfall) (EDHREC)

{X}{U} Instant Tap X target nonland permanents.

Are you play Gridlock as face down?

Relevant rules passage:

111.5. If a spell or ability would create a token, but a rule or effect states that a permanent with one or more of that token’s characteristics can’t enter the battlefield, the token is not created. Similarly, if an effect would create a token that is a copy of an instant or sorcery card, no token is created.

So Myrkhul should trigger, but the effect should do nothing. On line 105 of the effect, it does assert that the card should be a PermanentCard.
