[BUG] SDK7 Preview shows Network Sepolia despite wallet being in Goerli

SDK7 Documentation says to test blockchain in Goerli
That's what i have been doing during SDK7 migration
However, when i do set my wallet to Goerli, the preview scene reports "Network Sepolia" in the lower right.

I have been seeing a number of issues doing preview work in Goerli, so I tried Sepolia.
However, there is no Mana faucet ( and Uniswap exchange isn't able to swap Sepolia ETH for Mana, USDC, etc.)

I request clarity about whether we should be using Georli (in which case it should say so on screen when we do) or Sepolia (in which case where to we get Mana, USDC, USDT for testin)
