Contract ownership is semi-renounced (passed to a contract)

TransparentUpgradeableProxy.upgradeToAndCall(address,bytes) (TransparentUpgradeableProxy.sol#116-119) ignores return value by Address.functionDelegateCall(newImplementation,data) (TransparentUpgradeableProxy.sol#118)
UpgradeableProxy.constructor(address,bytes) (UpgradeableProxy.sol#24-30) ignores return value by Address.functionDelegateCall(_logic,_data) (UpgradeableProxy.sol#28)
Ensure that all the return values of the function calls are used.

BEP20UpgradeableProxy.constructor(address,address,bytes).admin (BEP20UpgradeableProxy.sol#8) shadows:
- TransparentUpgradeableProxy.admin() (TransparentUpgradeableProxy.sol#70-72) (function)
Rename the local variables that shadow another component.

Modifier TransparentUpgradeableProxy.ifAdmin() (TransparentUpgradeableProxy.sol#53-59) does not always execute _; or revert
All the paths in a modifier must execute _ or revert.

Different versions of Solidity is used:
- Version used: ['>=0.6.0<0.8.0', '>=0.6.2<0.8.0', '>=0.6.4']
- >=0.6.2<0.8.0 (Address.sol#3)
- >=0.6.4 (BEP20UpgradeableProxy.sol#2)
- >=0.6.0<0.8.0 (Proxy.sol#3)
- >=0.6.0<0.8.0 (TransparentUpgradeableProxy.sol#3)
- >=0.6.0<0.8.0 (UpgradeableProxy.sol#3)
Use one Solidity version.

Pragma version>=0.6.2<0.8.0 (Address.sol#3) is too complex
Pragma version>=0.6.4 (BEP20UpgradeableProxy.sol#2) allows old versions
Pragma version>=0.6.0<0.8.0 (Proxy.sol#3) is too complex
Pragma version>=0.6.0<0.8.0 (TransparentUpgradeableProxy.sol#3) is too complex
Pragma version>=0.6.0<0.8.0 (UpgradeableProxy.sol#3) is too complex
solc-0.7.0 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Low level call in Address.sendValue(address,uint256) (Address.sol#53-59):
- (success) = recipient.call{value: amount}() (Address.sol#57)
Low level call in Address.functionCallWithValue(address,bytes,uint256,string) (Address.sol#114-121):
- (success,returndata) = target.call{value: value}(data) (Address.sol#119)
Low level call in Address.functionStaticCall(address,bytes,string) (Address.sol#139-145):
- (success,returndata) = target.staticcall(data) (Address.sol#143)
Low level call in Address.functionDelegateCall(address,bytes,string) (Address.sol#163-169):
- (success,returndata) = target.delegatecall(data) (Address.sol#167)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
