Settings revert when updating hikashop

-- HikaShop version -- : 4.7.4
-- Joomla version -- : 4.3.3
-- PHP version -- : 8.1

Hi! The last 3 times we've updated hikashop on our Joomla site, several of the settings have reverted to defaults, mainly the contact email addresses, the currency (from USD to EUR), and thumbnail size settings. We've used the Joomla update dashboard, the update from inside the hikashop component, and I've tried downloading the latest version and updating manually, each time these settings were changed after updating. Is there any way around this, or do we just have to reset them after each update?
