Opencart language link extension en-gb to en 2.3.0.2

Hi in the past i was have opencart 2.1.0.1
Now i make an update to 2.3.0.2 and all links from myweb.ro/en/ have extension myweb.ro/en-gb/
I need a way to change that extension link from myweb.ro/en-gb/ to myweb.ro/en/
I tried to change name folders and doesn't work...

Thanks

would NOT be advisable, Language Codes are better to be used according 'standards'.
