Reflections and holders distributions on Testnet

Hi Everyone,
I am experiencing with many ERC20 tokens to learn the way they work, using Remix and Testnet environment.
I deploy the contract on testnet, add liquidity through https://pancake.kiemtienonline360.com/ and do buy/sell transactions just fine, however none of the distributions is working and this is on many tokens I tested.
Holders of the tokens don’t get any reflections and no tokens get distributed to the different wallets (marketing, charity or burn)

:1234: Code to reproduce

My last test was experiencing with the smart contract of SportemonGo, please find it here deployed in the testnet.

Remix, Testnet

I'm facing the exact same issue!
Please let me know if you fixed it or if you get the answer from anyone?
