New languages created with Polylang not changing currency

Hi,

This site had previously been using an old now obsolete plugin (Polylang Currency Converter). This would allow us to add a currency Symbol to each language. This is out of date so we have swapped it out for your plugin, we have used your plugin before and it has worked great.

The Problem:
The current languages that were created by Polylang seen to be working fine and i have tested changing English GB to use euros and back again, this works as it should.
However when I create new languages in Polylang such as English US it doesn’t change the currency symbol. I have tried this with a few languages and currencies and no new languages seem to respond to changes in your plugin.

Can you help me identify what the issue is please.

Thanks, Chris.
