Wrong contract storage with tuple keys

[tupui]

I have the following types:

#[contracttype]
pub enum CollectionKey {
    Collections,                // vec contract ID
    Collectibles(Address, u32), // (contract ID; Token ID) - Owner
    OwnerCollectibles(Address), // Owner - (contract ID; Token ID)
}

On lab it does not show properly the key if it is a tuple. See on Stellar.Expert the correct behaviour.

And this is what we have on lab
