Wrong test coverage of one specific method in coverage report

What was wrong?

I have the simple initializer function

    function initialize(
        uint256 _overtimeWindow,
        uint256 _auctionDuration,
        uint256 _minStepNumerator,
        uint256 _authorRoyaltyNumerator,
        address _payableToken,
        address _nft,
        address _adminAddress,
        address _treasury,
        uint256 _feeTokenNumerator,
        uint256 _feeETHNumerator
    ) external initializer {
        require(
            _adminAddress != address(0),
            Errors.ZERO_ADDRESS
        );
        require(
            _payableToken != address(0),
            Errors.ZERO_ADDRESS
        );
        require(
            _nft != address(0),
            Errors.ZERO_ADDRESS
        );
        require(
            _treasury != address(0),
            Errors.ZERO_ADDRESS
        );
        _admin = _adminAddress;
        payableToken = IERC20(_payableToken);
        nft = IERC721(_nft);
        treasury = _treasury;
        setAuctionDuration(_auctionDuration);
        setOvertimeWindow(_overtimeWindow);
        setMinPriceStepNumerator(_minStepNumerator);
        setAuthorRoyaltyNumerator(_authorRoyaltyNumerator);
        setFeeTokenNumerator(_feeTokenNumerator);
        setFeeETHNumerator(_feeETHNumerator);
    }

I cover all the code and branches with my code

But I see in the report Auction.initialize - 50.0%

But in the coverage GUI I see that coverage and branches report are all GREEN:

All other methods in the contract are OK

It looks like coverage report in text gives me 50% instead of 100%

[vsmelov]

Also note that all setSomething(...) methods which are called from inside the initializer are also 100% covered

    Auction.setAuctionDuration - 100.0%
    Auction.setAuthorRoyaltyNumerator - 100.0%
    Auction.setFeeETHNumerator - 100.0%
    Auction.setFeeTokenNumerator - 100.0%
    Auction.setMinPriceStepNumerator - 100.0%
    Auction.setOvertimeWindow - 100.0%
    Auction.setTreasury - 100.0%
    Auction.initialize - 50.0%

It was gone after I remove initializer modifier, but it still looks like a bug

Code coverage is definitely broken. Seeing similar and worse problems on Vyper.
