Most contracts use the delegateCall proxy pattern and hence their implementations require the use of initialize() functions instead of constructors. This requires derived contracts to call the corresponding init functions of their inherited base contracts. This is done in most places except a few.
The inherited base classes do not get initialized which may lead to undefined behavior.
Missing call to __ReentrancyGuard_init:
Collateral.sol#L35-L37
PrePOMarketFactory.sol#L16
Add missing calls to init functions of inherited contracts.
