bug when opening configuration page in dashboard

-- url of the page with the problem -- : http://localhost/CANERP/administrator/index.php?option=com_hikashop&ctrl=config
-- HikaShop version -- : 4.0.0
-- Joomla version -- : 3.8.13
-- PHP version -- : 7.2.10
-- Browser(s) name and version -- : chrome 69.0.3497.100
-- Error-message(debug-mod must be tuned on) -- : unexpected if in administrator\component\com_hikashop\classes\field.php line 657

fixed by adding } at the end of line 647

you'll see page not loading correctly, then following the error report, I see a } is missing?
