Cannot buy NFT with ICO coin. Wallet not connecting with ICO shortcode

When trying to buy an NFT with a token created through WPSmartContracts ICO feature— The Confirm button on MetaMask is greyed out – so the transaction cannot be completed. I have this ICO token set to be the payment method on the NFT collection. It shows up on the NFT pages and balances show as well… just cannot seem to complete a BUY.

I noticed a new message previously not there:

Warning! Are you using a reflection token? If so, you must exclude the NFT contract in your reflection token

Does this mean I cannot use a coin minted through WPSmartContracts as a payment method? Do I need to use ETH or other ERC-20 token? Xdai is preferred if possible.

If so what contract address do I use for ETH? How about xDai?

Also cannot access the Wallet when using the ICO shortcode presentation. The original Coin page does connect to the wallet OK though.

Thanks
