Incorrect currency position for shipping

Hello,

I’m working on a site that uses the WCFM Marketplace plugin and the issue I have is that the currency position is incorrect for “Add X amount for free shipping” in the checkout review order table.

Here is a screenshot of the Currency settings:

And here is a screenshot of the checkout details:

So it happenns only on that specific location, all the others work fine.

The WCFM plugin is updated as well as the others on the site.
The issue remains across different themes as well.

Do you have any suggestions on how to fix this?

Thank you!
