Your language file is not up to date message persists after loading lang file

-- HikaShop version -- : 6.2.0
-- Joomla version -- : 5.4.2
-- PHP version -- : 8
-- Error-message(debug-mod must be tuned on) -- : Your language file is not up to date. Load the latest version from our server
I know, don't remind me

I have just updated to Hikashop Business 6.2.0.

I got the message " Your language file is not up to date. Load the latest version from our server
I know, don't remind me"

I loaded the language file and saved it successfully, however I still get the same message when I go to Hikashop Configuration.

I have cleared the Joomla cache but no difference.

I have not added a language - current language is en-GB. This is the only language installed.

Please advise action.

Thanks and regards
Brett
