Upgrades with Down the Rabbit Hole (DtRH)

[GabrielCurubeto]

Hello,

In a deck with DtRH and 2x Arcane Research, I first upgraded Deny Existence from level 0 to level 5, costing 2xp.
Next I upgraded Clairvoyance from level 3 to level 5, which should cost 1xp due to DtRH, but is costing two experience on the website. The same happens if I try to upgrade Azure Flame from level 3 to level 5 instead.

Thanks,
