Can someone check the code for my ERC-20 ! Trying to add 1% buy limit but not working

Hello,

Im trying to create a token with 1% buy/sell limit and 1% maximum Hold but be able to switch it off later but when I test the code I still able to buy more than 1% . Not sure where is the mistake

​

I released a token on BNB for test (for cheap gas fees) but was able to buy from another wallet more than 1%
