Could Not Reproduce Bello, Bard of the Brambles ability still works when enchanted by Kenrith's Transformation

[Crouchsnap]

The text on the card reflects that the ability is 'lost', but it's still turning artifacts and enchantments into creatures.

Tag applied: Not A Bug

As stated by the Rules from WotC:
"If an effect causes Bello to lose all abilities during your turn, its effect will still apply to non-Equipment artifacts and non-Aura enchantments you control.
