when using Pancake Swap

I have in MetaMask, Binance Smart Chain, some Safemoon Coin.
When I try to add, via Pancake, additional SM coins it works nicely, when I try to swap back it gives give me 0 BNB a transaction result, I pay the fees, but I doesn't load any moon.

No file, test, or entry point is identified. Start by reproducing the reported Pancake Swap transaction in MetaMask on Binance Smart Chain, recording the transaction details and conditions; done means determining whether the zero-BNB result is caused by the app and identifying a reproducible failure scope.
