I had the same issue, resolved it by following this: https://github.com/PrestaShop/PrestaShop/issues/14595 I had to create another currency and disable the default, then re-enable the deault, and making the new currency inactive. Secondly I edited the database currency table precision 6 to 2 decimal places.
